Info Center Introduction

Welcome to the Sid Meiers Civilization IV Information Center!

Box ShotThis information is meant to give anyone a deep, factual understanding of Sid Meier’s Civilization IV (the sequel

Sid Meier’s Civilization III
) as well as Civilization IV: Warlords
(the first expansion pack of the base game). The article will keep up to the very last detail of information that is

currently available to us.

Material is gathered from all sources available (in a detailed manner) and

put into this article as one organized piece. This should make it very easy to find virtually everything you want to know,

without having to surf

through multiple places on the web to find what you need. You don’t have to be a
Civilization III
veteran to understand what we are talking about here,

since this is a brand new Civilization… a historical simulation/strategy game series which has won multiple game

awards, and which is


the world over as being the greatest, and finest turn-based strategy game series on the planet!

The game has been released, but it does not mean that this article will not
be updated with more news as it comes (patches, expansions, etc)!
This information is up to date as of Monday, July 3rd, 2006, and up to the latest available bit of information.

As information changes, or is released, I will be updating this as soon as
possible so it evolves to be factual. I recommend that you check out the updates
(when they are posted), so that you stay informed, and up-to-date as well.
Checking the “Miscellaneous Information" section
occasionally can also give you a heads-up on some other things either in regards
to this article, or other information. From what we have gathered so far, as
well as the great reviews the game has been receiving, I believe we can all form
our own opinions of it.

This is the most detailed and extensive, most viewed, and also the most
updated place for all things Civilization IV from around the web.

Currently, there are a total of 360+ gathered game details, with nine

new additions! Don’t miss out, discuss the article!


Newest Updates

This is the section for looking up all the current new updates on the go
from Monday, July 3rd. They are not organized in any way, so it is highly
recommended that you read through past this section and take a more in-depth
look at the rest.

  • Patch v1.61 has been released. There are many changes, fixes, and additions.
    Its size is 45.7MB and can be downloaded here.
    The SDK and PitBoss are also available. Get these here.


Civilization IV: Warlords

This is the first expansion to

the original

Civilization IV. It is due out this summer, in late July (2006).


The Big Picture

Here we’ll look at the very basics of the game, from its creators and the design elements they implement, to what

general game-play aspects


will contain.

  • Development & Producers: The new Sid Meier’s


    IV was

    developed by Firaxis Games (based in Hunt Valley, Maryland, U.S.A.).
    It is much more streamlined and full of personality. Unlike the Civilization III series, the publisher will not

    be Atari, as they have sold off the Civilization Franchise to Take-Two Interactive. Take-Two confirmed this on January 26th, although it has been known that Atari sold

    the Franchise since

    November 24th, 2004. The game was published under Take-Twos publishing label 2K Games.

    The senior producer of the game was Barry Caudill (he produced Sid Meier’s Pirates!), and the producer Jesse Smith.

    Jesse was the producer


    Civilization III: Conquests as well (the last, and most commendable expansion of the
    series). The project lead, and lead designer

    of the game was Soren Johnson, he programmed and co-designed Civ3 along with company CEO, Jeff Briggs. For more

    information on Firaxis

    staff, check out the Bios section on their


    • About 38 people have been dedicated to certain segments of Civ4 (terrain, cities, interface, etc). It will

      take thousands of people


      to complete the project. Firaxis also says that they have many (100+) active Civilization fans testing and giving

      feedback to Firaxis.
      This number is rising. However fans have been giving feedback since

      June of 2004 in a private online forum.

    • News that Civilization IV was in the very early stages of development first came on December 4th, 2003.

      Development of

      likely started around Spring time in 2003 (more than two years ago). At around the Fall time of the same year, Firaxis had

      an early Multiplayer


      up and playing. The basic game-play elements were established then. After that period (around May of 2005) much more

      attention has been given to

      improving the AI (or Artificial Intelligence).
      The game hit Beta in August and from
      then on, much more attention was given to polishing up the different
      aspects of it. Civ4 went Gold on

      October 19th, and shipped on the 25th, although most people got

      their copy on October


  • Good news for Macintosh Gamers! Civilization IV
    will be available for the Mac in early 2006 [source]. Aspyr Media
    is bringing the game to the Mac. Civilization III: Complete

    (featuring both expansions of Civ3: Play The World and
    ) will also be available for the Mac later this year, in December.

  • Firaxis Memo: Firaxis has updated their “Behind the Scenes” section on their
    website with a new Winter-edition Memo. The

    part below includes

    content on


    Civilization IV has been flying off the shelves and has received loads of
    great reviews. We want to thank our fans for your unwavering support, and
    particularly for your tremendous feedback that helped get us through some
    initial technical issue right after the release of the game. Our team worked
    tirelessly to fix the problems quickly and post a
    patch to
    help those folks experiencing difficulties in running the game. Civ fans are
    truly extraordinary! And dont forget… Santa will be bringing another gem of
    a gift in January… the Civ IV SDK! This is an unprecedented offering and we
    cant wait to see what all of you budding Civ designers will create!

    • Civilization is much more of collaboration between
      our designers and our fans. We’ve had a lot of feedback over the years about what works and what doesn’t in Civilization

      and it’s had a big

      impact on the

      ” – Sid Meier said in a GameSpy


    • Many conventions which have remained the same since Civilization I (which came out in 1991) have been

      to ensure a quality new game.

  • The game was written entirely from scratch using flexible XML data files, as well

    as the

    Python scripting language. Boost.Python (this allows for seamless interoperability between C++ and the Python programming language)
    was used as the

    interface layer between the C++ game code and Python. Python is used in the game for map generation, interface screens,

    game events, tools,


    etc. If you want to see how this will affect customization of the game (or any other aspect relating to customization),

    look under Customization Flexibility. The new 3D engine will also allow for greater possibilities (find

    under A New Expression).

  • Firaxis main focus is aiming to keep the game true, simple, but mostly to lose

    aspects which are not

    fun (find


    Controlling Your People… by Decree for aspects which have been removed because they are

    not fun to the player),


    to maintain a successful Civilization Franchise.
    They also plan to break free of some bad habits from previous
    titles. For more information on maintaining a successful Franchise, see the PowerPoint entitled

    Dont Blow It!, by lead Civilization

    designer, Soren Johnson. An article that relates to the PowerPoint is “Civ4: A Model in

    ” where Soren talks about the challenges of improving on a
    successful model while simultaneously keeping hardcore fans satisfied. That being said,
    will not be totally different in concept than

    Civ3. Don’t let this fool you into thinking that it will just be a small improvement over
    , though! Remember, it is

    rewritten from scratch, so there is a lot of change/alteration and major innovation.

    • In order to fight team fatigue, Firaxis will rotate its design responsibilities (with different lead


    • Firaxis will not be afraid to slightly change its target audience a bit, as keeping the same audience will lead

      to the loss of a


      percent of people per cycle. They will still, however, make base fans comfortable with the same fonts, icons, and map

      placement, a similar number


      units on the screen, etc

    • Civ4 being a maturation of the franchise (since it will focus on more multiplayer, and modability, unlike

      , as it was

      under a lot of pressure), they will keep adding more game-play/design innovation and not just adding more content or

      “Stuff.” Making everything a

      little better will be much less compelling to the player than a significant improvement in just a few areas. Soren also

      Electronic Art’s (EA’s) Bing Gordon that “1/3 old, 1/3 improved, and 1/3 new” is a good rule of thumb. Simplifying

      old systems will leave


      for new design elements.

    • Firaxis will also “borrow” useful elements mostly from Real-Time Strategy (RTS) games. An example with
      was the distinct

      civilizations, unique units, abilities, and multi-unit forces or armies.

  • Civilization IV will continue on to what Civ3 has had
    The core game-play concept still remains the same. It is a turn-based, tile-based, historical simulation/strategy

    empire building game. You

    are put as the emperor of a powerful civilization, ruling your empire by decree, with one goal in mind: to stand the test

    of time (which has been


    appropriate slogan of Firaxis). You start out with a small tribe and lead them to greatness, to the post-nuclear age and


    • The game is even more about strategy than ever.
      It is more about decision making and less about the established motions that have built up over the years.

Release Date

Perhaps this is the most important question to most people. When will the game actually be released?

  • Take-Two Games has pushed the release of
    Civilization IV up by a few weeks.
    The game was released on October
    25th, although most people didn’t get the game by the 26th in North America. Click

  • Expansions are planned, and support for the game will

  • A Mac version of the game is also planed by Aspyr Media.
    It will be available in 2006.

This section will deal only with the Official System Requirements for the game, as well as the ESRB Rating.

  • The Minimum System Requirements for the game are: 1 GHz CPU, 256MB RAM, and a 32MB video card with hardware

    transform and lighting


    The recommended Specifications are: 512MB of ram, Pentium4 processor, and a recent graphics card (like the Radeon


  • The rating of the game is “E 10+” by the ESRB (the
    Entertainment Software Rating Board).


A New Expression

The look and feel of a game are very important to most players; the description of these can be found here. For

screenshots, visit the “In-Game Visuals” section.

  • The Graphics Engine Civilization IV is using is
    the NDL’s Gamebryo 3D graphics engine. Firaxis’ PC hit,
    Sid Meier’s Pirates!
    also uses it.

    • The engine will naturally provide an engaging 3D world with unparalleled scope and detail. Soren also mentions

      in his PowerPoint
      that the game has a “What-you-see-is-what-you-get,” approach to it, meaning that the terrain does not lie in terms of

      what it displays. An

      example of this

      Great Wonders. When they are built they will be displayed on the terrain near the city which built it.

    • Rivers and resources such as horses and elephants
      are animated. You will also see different

      animations as
      the resources are being worked on, and of course, many other aspects which make the world more dynamic.

    • Due to the move to 3D, Barry Caudill (senior Civ4 producer) says that the largest maps in the game
      are slightly smaller compared to those of
      Civilization III.

    • The new 3D engine will allow for powerful, smooth zooming, from a global level, to a very local one. The tiles of

      are plain

      squares, rather than the diamond view we had with Civilization III (when
      viewing the game from the default position). The
      Camera views are very flexible. You can spin it around any way you like.
      There is a Civ3-Style Isometric view, and the classic
      Civilization I
      top-down view. You may zoom in and out by using the Mouse-Wheel (speaking of Mice,

      Civ4 will even have its

      own specific


    • You’ll see
      Aqueducts go from the mountains or hills into your cities when they are


  • A Random Map Generator, like previous Civilization titles,
    will form unique worlds reflecting the settings you put in. The Map Generator is one of Civilization’s most

    successful aspects, because


    cannot play on the same map twice without wanting it, so replayability is very, very high.

  • Continents are the default world setting. “Standard Size” map you will have about five to ten cities. By that

    time, your borders

    are established and it is a race of who can advance through the tech tree faster. By that time, your oldest few cities will

    also be the “core”

    cities of you empire.
    Here are the different map sizes: Duel, Tiny, Small, Standard, Large, Huge and
    of course, Random. There are no restrictions on the number of Civilizations you
    are allowed to play with on a certain map size. You can have all 18 Civs on a
    Duel map. The map widths in Civ4 are about double than what they used to
    be in Civ3.

  • The Mini-Map starts out zoomed in when the player starts a new
    random game. As they explore, the Mini-Map will expand. This has been done so exploration is a lot more interesting each

    What it means is that when one starts a game, he or she does not know exactly
    where on the map they are. In
    the player always knew where they were exactly
    in the beginning. Now this is not the case at all.

  • There is a Global View, in which
    you see the whole planet. There, you can also use options to filter thing
    such as resources, units, trade networks, cultural borders, religions and
    more. Below are three

    examples of the powerful new zoom. Details such as cloud cover can
    also be seen in the Global View (first image):

  • Music for Civilization IV is also a major focus. Jeff Briggs (Firaxis’ CEO) himself is taking charge

    of this aspect of the

    game (and
    he is perfectly suited to do so as well, since this was his first career). Jeff anticipates that

    Civ4 will have much more music than any
    other game ever released. The game will include music from some of Jeff’s original compositions, as well as licensed

    performances by old greats
    such as Bach, Mozart, Beethoven, company, as well as contemporary greats like John Adams and Christopher Tin. Here is

    opening soundtrack: Baba Yetu.

    • Jeff will also be composing the music for all 28 wonder movies included in the game as well as all of the game’s

      diplomacy music.


      folk tunes are used to represent the character and attitude of each Civilization and each ruler. The music for Franklin D.

      Roosevelt for instance
      is the Marine Hymn. Jeff has also gone as far as to arrange each piece of music to fit the various time periods of the

      game. If you meet with
      Roosevelt in the early part of the game, you’ll hear ancient instruments playing the theme. By the end of the game, the

      tune will have swelled

      taken on a more Sousa-like quality.

    • Firaxis is also hiring voice talent for various game parts. Ambient sounds can also be heard, when you are over

      different terrains. For


      if you are over the ocean or on its shore, you will hear waves splashing and breaking up. When you are

      over desert closer up, you will naturally hear very dry winds.

    • When clicking on a unit, that unit will respond in the language
      of your selected region or Civilization.

    • With each built improvement you’ll hear a sound related to it
      when it is accomplished.


User Interface & Control

Control is a very important aspect for any game. With Civ4’s new interface, ruling you empire just got a whole lot


  • To start a Single-Player game: You must choose your map style (some
    options are: Archipelago, Continents, Custom Continents, Highlands, Great Plains, Inland Sea, Lakes, Oasis,
    Pangaea, and Terra) and size, climate and sea level and Civilization you want to play. You can also select whether you

    want aggressive AIs,

    Random Personalities, etc. Also, AI personalities are stored in XML data files.

    • In the "Custom Game" menu (there is also a "Play Now!" option which allows you
      to start games quicker) there are a variety of options and combinations. In
      regards to map scripts there are much more. The "Custom Continents" option
      allows you to select exactly how many continents you want in the game. The

      "Highlands" map scripts allows you to select everything from mountain density to
      lake size. Of course, the most random map options you have are the classic
      "Archipelago," the basic "Continents" setting, as well as the regular "Pangaea"
      option which allows you to also set in different shore options.

    • There also the “Aggressive” AI setting where

      AIs lean towards war instead of diplomacy.

    • While in the process of loading, the game

      will display tips for certain things from Hot-Key commands to strategies during war-time. Here is a screenshot which shows some of

      these. Note that when

      the game

      actually starts, you have a very similar Civilization introduction as in Civ3. You can see what I mean by clicking


    • At the start of the game, you do not start

      with a Worker unit as in Civ3. You must build your first one at the time of your own choosing. Note that whenever

      building a Settler or

      Worker, these

      units both use Hammers and Excess food to be built instead of Hammers only. The city also does not grow during this period,

      and when either of

      the units is

      complete, the city size does not shrink like it used to in Civilization III.

  • The Civilopedia is now available from the

    main menu of the game for easy access.

  • The general layout of the interface is this:
    The Mini-Map is on the bottom-right corner, unit statistics are on the bottom-left side, unit control and buttons
    are on the bottom

    center of the screen. On the top-right, we see a “?” sign (which indicates the
    Civilopedia. The Civilopedia is like the game’s manual. It includes all
    available information on the game) as well as the year and era. Technological

    research are located on the top, in the center. And finally the scientific research rate buttons
    are on the top-left side. On the same side,

    you can also find your income and Gold Per Turn (or “GPT”). There also appear to be landscape
    characteristics on the bottom-left side. This most likely appears as the
    player rolls over the terrain with the mouse. Here is a screenshot of the
    lower portion of the interface only. For City interface information, click

  • In
    Civilization IV you can left click on a unit,
    and then right click on the tile youd like that unit to go.
    This is very different compared to Civilization III.

  • Advisor screens: depending on which you open, you can see where all of your units are on a global map, or look at

    raw statistics like the

    average life expectancy of your people (versus the world average), your gross national product or approval rating.

  • Shanghai building a Market A more streamlined and intuitive interface should be familiar to any RTS player. This is one

    feature that will make


    franchise more accessible and in line with PC gaming trends. In general, the
    interface and help screens are more modern, improved, and easier to use.

    • Many tool-tips and pop-up help features are available (such as the terrain characteristics I explained just above,

      and the ones you can

      see in

      the screenshot). Firaxis feels you should be able to play from the main map, and use other screens only if you are a true

      power user. All this is


      at getting new players off and playing as quickly as possible. Again, this is
      the "what-you-see-is-what-you-get" concept. Below, in the next section, you
      will see that this concept is carried onto the Terrain Improvements as well.
      They will basically animate if a citizen is working that tile.

    • Sid Meier’s Tips on tool-tips (such as Units

      and Technologies) are included. This option can of course be turned off via the preferences screen. The preferences screen

      also allows the player

      to enable

      Single-Unit graphics instead of Multi-Unit graphics.

    • Numerous Advisor pop-ups also appear during the game which will recommend to you to build a certain building in a

      particular city or

      town. You can disable

      these if they are unneeded to you or become too annoying.

    • The game will prompt you to construct
      improvements if it sees an opportunity or it feels that you’ve missed an

  • Playing the game either with a keyboard only

    or mouse only is easy (or you can of course use the two combined).

  • By default you’ll be moving units with the

    right mouse button. However in the preferences section, you can change that so you can move units with the left mouse

    button and have a

    right-click menu when

    clicking the right.

  • Wide-Screen resolutions are supported (as well as any other
    resolution you might be running your PC on. Civ4 also supports
    Dual-Monitor play. The game has to be in windowed mode and you have to give it a
    resolution which covers both screens.

  • Hot-Key commands: Just about 100.

  • City information such as its buildings, and workforce is now all accessible from the main screen. You
    are able to see what a city is building as well, including what state of religion it is in
    (although Cities can have more than one religion). To the right is an example of Shanghai building a Market. It is also Buddhist (as the icon above the city name displays).

  • Adjusting what you want to displayed on the map is easy. This includes city names and
    sizes. You can limit everything to a maximum and allow only Units, Cities (with no names), and Roads
    to be displayed. You can also turn on an option to display the properties of
    different tiles, you will also be able to turn on a resource plot location
    feature, mentioned here.


Landscape Characteristics

To expand your empire, first you would need as much detail about the terrain as possible.

  • More tile/terrain improvements are

    included (each resource has its own specific improvement). Pastures, Wineries, Watermills, Windmills, Lumber Mills, Mines,

    Fishing Nets, Offshore


    and Factories
    are all represented in detail on

    the terrain. 20 improvements in all are going to be included. Improvements being worked on with citizens will animate,

    which makes it convenient

    to see

    where your citizens are working. For example, if a Mine is being worked on by
    a citizen, you will see smoke coming out of its chimney.
    Details such as mine carts being pushed out of a mine are also available.
    This interface feature even helps you during war time, allowing the player
    to see which tile an enemy is using. Certain Technologies will make some

    improvements more productive as well.

  • Roads and Rail-Roads will only provide a movement bonus
    to your units and nothing else. This has been done so the player does not have Roads and Rail-Roads on every tile later on
    (unlike in Civilization III).

    Tribal Village

    Provides bonuses such as more
    experience points for the unit that uncovered it, maps, technologies,
    etc. (Goody Huts, or Tribal Villages,
    cannot be built by the player.)
    City Ruins Sites of razed cities remain on the map
    (when you first capture a city, you may raze it, however this can be
    turned off so there is no city razing).
    Worked Tile Worked tiles have their own animations and icons.
    For example, if a Quarry is worked, the crane will move. If it is not,
    the crane will not move.

  • There are many new resources. When you are zoomed out to
    the Global View, resources are

    clearly marked for easy identification if you choose to mark them.

  • There is less restriction when it comes to resources. Firaxis will probably give players something to

    synthesize Oil, and Gunpowder


    no longer

    require saltpeter.

  • All resources, including food ones are tradable. Food resources will help your city’s health status.

    • Securing the seven types of food resources can also lead your
      cities to become more healthy, as they represent nutritional variety. Each
      different food resource decreases your unhealthy population by one.

  • Better resource balance: Since Python Scripts are used to generate random maps, resource placement can be

    fine-tuned. This means

    that a

    resource of
    one group cannot be a certain distance from a resource from the same group (comparing
    luxury with luxury, food with food, strategic with strategic).
    The Civ3 dilemma where one faction gets more resources than another seems to be gone. Resource migration will also

    not happen

  • Trading is established automatically when you make deals. Rivers are like roads in

    Civ4 (in terms of their trade potential), so if two cities are on one river, they are

    connected and no road is needed to establish the particular trade network.

    • Due to the expanded aspect of trading

      involving Rivers (making them like roads in terms of connectivity), City placement in
      is made much more strategic. If a

      river connects to a lake, then a worker is able to build a road to the lake and expand the Civilization’s Trade

Victory or Defeat?

It all comes down to this: Achieving it against the AI earns you ego. Achieving it against another player earns you


  • There are a lot more difficulty levels than in previous Civilization games.
    Settler, Chieftain, Warlord, Noble, Prince, Monarch, Emperor, Immortal, and
    Deity are the available difficulties now.

  • The length of games is reduced from 540 turns (as in

    Civilization III) to 430. You are able to start in any era you wish
    (Ancient, Classical, Medieval, Industrial, Modern, Future. You start with a
    different amounts of units in each era, you will have more population in
    newly founded cities, as well as a few more buildings). Later era starts will give you larger starting cities, more

    settlers, and of course

    more techs. They will also have some limitation – earlier wonders and buildings may not be available. The developers

    are also constantly working to even out the pace of the game, hence the speed options described below.

    • There are four game speeds: Quick (mostly for Multiplayer, in Single Player mode (or

      SP) it is equal to

      Civ3‘s Accelerated Production mode), Medium (a bit faster than Civ3,
      15-20 hours of game-play), Epic (around 600 turns) and Marathon (introduced
      in patch v1.52). All of the game speeds (Quick, Normal, and Epic) retain all the flavor of Civ itself. So even
      though the speed is different, the feel will not change.

    • The different speeds of the game (Quick, Normal, and Epic) will
      have their Technology costs, Unit production costs, and Building appropriately tuned for the appropriate speed of the


    • The game still spans from 4000BC to 2050AD. That means you have 6,050 years to achieve one of the victories


    • Civilization IV seems to have struck the balance between explored land and years passed. What this means

      is that no longer will

      you have the entire world explored by 400AD. This, by the way, is the same for all three speeds (Quick, Medium, &


  • Most of the victory conditions have not changed from Civ3.
    Here they are:

    • The Time Victory: One can win this by having the highest score at 2050.
    • The Conquest Victory: By eliminating all rival Civilizations, you have achieved this victory.
    • The Domination Victory: This is awarded when you have a 25% lead in population over their best competitor, and

      65% of the global land


    • The Cultural Victory: You can achieve this by having three cities with a
      50,000-point Culture rating.
    • The Spaceship Victory: Having first built all the components of a Space Ship and launching it to Alpha

      Centauri, earns you this


    • The Diplomatic Victory: After building the United Nations Great Wonder, your Civilization is voted on to take

      control over that

      organization. Since it is

      difficult to maintain good relations with all Civilizations (especially in large games), this is possibly the most

      victory condition to achieve.

      Click on the United Nations link for more information
      on that wonder.

  • Winning the game also gives you a movie (no matter how you chose to win it).
  • The Spaceship (which is required for this) contains about a dozen components

    total. Some of the parts are: SS Casing, SS Cockpit, SS Docking Bay, SS Engine,
    SS Life Support, SS Stasis Chamber, and the SS Thrusters. You may boost production on this by constructing Laboratories in

    your cities or by

    construction the Space Elevator Great Wonder, which boosts Spaceship

    production in all of your cities.

  • The game will calculate a running score for each Civilization. This is based on
    the following details: Civilization size, technology, military power, and more. If

    you leave your Civilization lightly defended or with obsolete units, other nations will take advantage of this.

  • There is still a replay at the end of the game (when it is won or lost), and after each game the replays are saved

    so you can later view

    them in the “Hall of

    Fame” and look at how well you did in different games. They show things such as the appearance of Great People, City

    foundations, Civs being
    wiped out, etc. The Hall of Fame screen not only remembers every game’s
    statistic under your profile (you can create different profiles in Civ4). It
    remembers Difficulty Level, Game Speed, Victory Achieved, Starting Era,
    World Size, Finish Date, as well as the Score Itself and more. It also saves
    every game’s replay so you can look back to any previous game which you have
    finished and watch how you developed. The score, by the way, is broken down
    in a detailed manner in-game as you move your mouse cursor over your name
    (the score is broken down to Population, Land, Technologies, Wonders, etc).
    These can also be saved separately from a regular game save and you can send
    these to other people.


The 18 Civilizations

There are a lot of opportunities in the game to form allies, and that is necessary to fend off enemies.

  • 18 playable Civilizations are featured in Civilization IV.

    • There are 26 world leaders. Choosing between two leaders for a
      Civilization is a possibility. You can choose from two leaders from each Civilization, however not every Civilization


      two leaders.

    • You can name the leaders after yourself, and
      pretty much name everything else throughout the game…

  • Unique Units for each Civilization are still in the game. Some of
    the known Unique Units (or "UUs") are below in the Civilization Chart.

  • You are able to see more of the leaders bodies, unlike in
    Civilization III
    , where one could not see them make hand and finger movements. An

    example of this can be seen when watching the “Game-Play

    Footage 2” video at GameSpot. Leader animations will also reflect their mood and natural personality.

    • An

      offer in
      the favor of Louis XIV or Hatshepsut will show animations of the leaders that suggest their happiness with the deal. They

      will simply act

      However some rulers are a bit more inscrutable. The only difference in personality you will see in the Chinese ruler, Qin

      Shi Haug is the

      of his eyebrows… the same as the Mongol leader Genghis Khan. Rulers like
      Alexander the Great of the Greeks and Julius Caesar of the Romans are much
      more expressive in their emotions. Julius will give you a gladiatorial
      thumbs-up or thumbs-down in reaction to your proposal. Gandhi is generous
      to weaker nations, while Genghis Khan will shy away from any diplomacy at all.
      Basically, there are a variety of unique personalities, some warlike,
      peaceful, trustworthy, etc. You can also select Random Personalities at the
      start of the game so every leader acts differently than what they usually do.

  • Units of different nationalities can now share tiles. If you have open borders with a Civilization, your units can

    literally go to any

    tile (even in Cities!).

  • All the known
    Civilization properties
    have been listed below. Each
    Leader has two Traits. Each of these grants them a unique bonus and cuts the
    cost of two city improvements by half. Here are the statistics, and both of
    the following charts are brand new:

    Trait Benefit
    Aggressive Free
    Combat I promotion of
    melee and gunpowder units. Double production speed of Barracks and Drydock.
    Creative +2 culture per city.
    Double production speed of Theater, Coliseum.
    Expansive +2 health per city.
    Double production speed of granary and harbor.
    Financial +1
    commerce on plots with
    2 commerce. Double production speed of Bank.
    Industrious Wonder production
    increased 50 percent. Double production speed of Forge.
    Organized Civic upkeep reduced
    50 percent. Double production speed of lighthouse and courthouse.
    Great People birth rate increased 100 percent. Double production speed
    of University.
    Spiritual No anarchy. Double
    production speed of the Temple.

    independent cities and small militias. They are like a “mini-Civ” that can cause trouble at any time.

  • Barbarians may also capture and control your

    cities as well as the obvious pillaging of your improvements if you find them in your territory.

    • Animal attackers (which pose a similar threat as Barbarians do), such as Lions, Bears, Jaguars and wolves
      are present early on in the



Artificial Intelligence

Perhaps a significant component of good game-play is a good AI. The AI is much improved in the new game…

  • Improving the AI has been a large priority. For months now, much focus has been dedicated to it.

  • The AI now seems to be blind. It does not know where certain things appear (unlike in Civilization III. On

    higher levels, the AI

    receives production bonuses. In the end, rest assured, you are playing against a smarter AI, not a more cheating


  • The AI is more interactive and it will contact you much more often for various things in its interest.

  • The AI will no longer attack in a few huge stacks of units. Instead you will now see the AI attacking in steady

    waves of units that just

    keep coming!

  • The AI attitudes toward you can be either Friendly, Pleased, Cautious, Annoyed, or Furious). This the reasons for

    this are, again, very

    clearly laid out in the diplomacy window.

  • Selecting AI Random Personalities is also a possibility at the start of the game. This way, you do not know

    how the AI will behave

    (Gandhi may not always be
    polite, and Genghis Khan may not be warlike!).

  • The City Governor AI will also be more improved to assist you better. And that is an important part, because

    it naturally allows

    you to

    micro-manage less. And another main goal of Firaxis is to kill player micro-management.

  • When in the
    Bargaining Table,
    you can now see why the leader’s
    attitude is the way it is. Here is a positive point in the relationship and attitude: “+1 Years of peace have

    strengthened our

    relationship.” Here are also a few negative
    points which may occur: “-1 Our close borders spark tension,” “-3 We are upset that you have fallen

    under the sway of a

    heathen religion,” “-1

    You have traded with our worst enemies!” These can be seen here.
    Basically, the positive points are: If you have the same religion with that
    Civ, similar Civics, resource trading, fair trade relations, years of peace.
    The negative points may be: If you have a different religion than that Civ, if
    you have traded with an enemy of that Civ, closed borders (they spark
    tension), refuse to stop trading with a certain Civ. Different leaders will place different weights on these factors.
    There are true hard feelings in this system, and it is much harder to simply
    bribe an AI in diplomacy in order to make it do what you want it to do.

  • The game is sped up thanks to faster AI moves during the
    Middle and Late stages of the game. Some features tended to slow down the late game.
    They have been removed (for example: pollution cleanup, city riots, and units disbanding due to money issues). This means

    the late game
    is just as

    to play as the rest of the game.


International Affairs


ScreenAbove, the AI and Diplomacy virtually go hand in hand. Both are also improved… which means a much more



  • The AI must respect your borders or declare war in
    Civilization IV.
    AI’s did not have to respect your border at all in
    previous Civilization titles. Look back at any game and most players will see frustration of how the AI

    kept wondering around in your own border, without you being able to do anything
    about it.

  • If you have a Defensive Pact with someone, and they get attacked, you will have the option to back down and

    not get involved in

    that war. This will
    of course damage your reputation, but remember that in Civ3 you absolutely had to get into a war
    no matter what.

  • Negotiating peace in diplomacy is now possible between two Civilizations which are at war with each other.

    On the other hand, it

    is also

    possible to make two other Civilizations go to war, even if you do not wish to get involved at all.

  • Your military still plays a large role in Civ4 however it has been balanced out with other options,

    such as diplomacy. A

    lot of
    emphasis has been put in in balancing different aspects of the game so the player does not focus on one
    aspect more than on another.

  • Trading made easy: There is a new screen that explains

    what other Civilizations have to offer and what they want to trade for (it also
    tells you what technologies and resources the AIs have). This is all in the
    foreign advisor screen. This screen also tells you the AI relations toward
    you, current ongoing deals, etc.

  • The player may gift units to the AI by moving a unit in their territory and pressing the “Gift” button which

    automatically makes that unit


  • The diplomatic victory condition is triggered by construction of the United Nations

    great wonder. When it is

    first constructed, a Secretary General is

    elected (every Civilization gets a vote during this. The builder of this does
    not automatically get to be the secretary General). If you get elected, you can get various resolutions passed.
    Here they are:

    • Free Trade – Free Trade removes all trading restrictions in the world between all

      Civilizations. It

      basically functions as if all Civilizations have open borders – No matter what their real diplomatic relationship may


    • Nuclear Non-Proliferation – As Thunderfall’s article has mentioned already, adopting this means that no nukes may be built, however

      existing nuclear weapons

      are not destroyed. Note that if this resolution passes before any nuke is built in the world, it means that the game itself

      will proceed without

      nukes appearing. This may be a benefit to you if you’re playing against aggressive Civilizations.

    • Universal Suffrage – All Civilization’s civics are changed to Universal Suffrage (+1

      Hammer from Town; Can

      spend gold to finish production) no matter if they have the required technology for that specific Civic (this counts for

      all UN Resolutions

      relating to Civics).

    • Free Speech – All Civilizations adopt the Free Speech Civic (100% culture
      in all cities; +2 gold from Town).

    • Emancipation – All Civilizations switch to the Emancipation Civic ((100%
      Growth for Cottage, Hamlet, Village; Unhappiness for civs without that civic).

    • Environmentalism – All Civilizations adopt the Environmentalism Civic
      ((+6 health in all cities; +1 happiness from jungle, forest).

    • And finally, Free Religion – All Civilizations Adopt this Civic (No
      non-state religion spread; +1 happiness per non-state religion in a city, +10%
      science in all cities).

    If you fail to get elected, you have to wait until the next election. You can use the UN as a diplomatic

    tool to force other nations to adopt certain policies which they normally wouldn’t.
    Note that after every three resolutions, a new Secretary General is up for

  • Building Spy units is possible just like in Civilization II (they
    now have a movement of two and cost 80 Hammers).
    The player is limited to the number of Spies you can have in the game. Before
    construction the player must have the following: Communism and the Scotland Yard
    National Wonder, meaning every Civilization may build its own (500 Hammers; +1
    Great People Points; More likely to generate a Great Scientist). You are allowed
    to have a maximum of four spies at any one time. They are invisible to other
    Civilizations just like Submarines. These units cannot be attacked or interacted
    with, however they can be exposed by rival Spies (you are able to expose enemy
    Spies as well). Other abilities of the Spy unit include:

    • Investigate City – This is rather basic. It allows you to have a peek inside an

      enemy city and see all

      its properties (what it is producing, Culture
      amount, what unit it has, etc, etc).

    • Destroy Production – If you order your Spy to destroy the production of whatever a city

      is producing (and if

      successful), half of whatever is being produced
      is destroyed (therefore slowing down dramatically production of, say, a Great Wonder). However, if the Spy fails, it is


    • Sabotage Improvement – If a Spy is ordered to do so, and if successful, a terrain

      improvement will be

      destroyed (such as a valuable Oil Well). If
      unsuccessful, the Spy will be destroyed.

    • Steal Plans – First of all, the Spy has a much better chance of having success at this

      if the action is

      taking place in a City which contains either a
      Palace (therefore the capitol of that Civilization), a Forbidden Palace, or the Versailles Great Wonder (Requires Divine

      Right; Reduces

      Maintenance in nearby
      cities; City in which it is built in is more likely to generate a Great Merchant; Doubled Production speed with the Marble


    The above actions need gold. Success depends on the amount of units the other Civilization has in the area of where the

    action is taking place.

    Nearby enemy spies
    also decrease the amount of success your Spy unit has.

  • Other Civilizations have different

    favored Government and Religious settings, and they will try to pressure players into changing to their favored religion or government to suit their

    desires in return for better relations with your Civilization.
    They can even ask you to stop using a Civics option you have set.

    • Leaders will appreciate other leaders that share
      their traits and civic or religious choices (as stated above), and they will tend to form blocs. If you find leaders that

      share your tendencies,

      it will be

      possible to form lasting
      (even permanent) alliances.

    • What you choose might affect other Civilizations as well. If you have already introduced Emancipation, it sometimes

      may lead to

      unhappiness and

      within other nations without Emancipation, but to you, it does not give a direct benefit (so it provides a negative aspect

      to other Civs, if they

      don’t have

      Also, if your Civilization is the first to outlaw slavery, that will create discontent in societies that have


  • In diplomacy you can try to make another civ adopt a certain Civic or a Religion that you have. However the AIs are

    much more focused on

    their own agenda.

    Some Civs care more of your type of religion, others care more about your Civics, others follow whoever has the most money.

    AI Civilizations can

    even call up

    the human player and ask him/her to stop trading with a Civilization they hate. This make the player make decisions which

    impact relations a

    great deal.

  • Filling in the blanks: You can put a deal on the table and then ask the AI
    leader to fill in the blanks, no matter what combination is out there. You can also tell when a deal would never happen

    because the choices will

    show up in

    red on
    the list. On a related AI note, Soren Johnson (the Lead Designer for the game) is now totally focused on tweaking the



Controlling Your People… by Decree

All the power is in your hands. What you do with it can lead to your Empire’s victory or your utter demise.

  • World

    Religion, Civics and Great People are things many people have suggested be put into the game, Soren has described these

    "killer" features in his PowerPoint. These are in Civ4, and they will have an influence on your whole

    empire. The factors

    which have


    domestic affect are described below…

  • Factors which are not fun in the game such as corruption/waste, rioting, pollution, and maintenance
    are started from scratch or removed

    (this means that they are replaced by a much better concept that maintains game
    balance better). Pollution is most affected. It was dumped,

    although not completely removed. A more extensive health system is something new, although no details about it have

    surfaced yet. Annoying

    micromanagement tasks will also be decreasing dramatically, and more high-level control
    is provided.

    • The concept of corruption has been

      replaced with
      maintenance costs. This time instead of Courthouses being able to reduce corruption (since it is gone) they will actually

      maintenance costs.

  • Cultural Power
    You will have to develop your culture or risk being enveloped by a larger neighbor (so a nation

    can be completely

    engulfed by another’s


    • The luxury slider is now a culture slider. The more culture you give, the happier your people will be, as well as

      producing more culture


      your entire Civilization, meaning it can also expand your borders more, the more
      you increase it (but at the expense of Commerce and Science Research).

    • Culture basically modifies your borders in relation to the culture of your neighbors, so you can overwhelm your

      neighbors with a



    • Culture now also increases a citys defensive value, and it helps smaller cities with more culture feel safer. Since

      it restarts when you

      capture a city, your top priority is to maximize culture in that city.

    • There is no more Cultural Dominance in flipping Cities. Instead, as your nation expands, foreign cities will begin

      to become more and more


      awe with your Civilization as a whole. This will cause the people in those foreign cities to get unhappy, and therefore

      their Civilization will

      have to

      spend money to keep them happy. As this burden gets heavier, that Civilization might just offer to give you their Cities

      via diplomacy.
      One easy way to counter unrest in your cities due to your neighbors having
      superior culture is to station more units into that city.

    • Culture essentially represents a “Soft Power.” This means that nations can defeat other nations through more



  • Health is just as important as maintaining your treasury and the happiness of your people. Health
    is tied to available food and

    resources to simulate Epidemics. However, if you have Fresh Water near you, it will give you a health


  • There is a lot of built-in automation in the game (also aimed at reducing micromanagement). Setting units such as

    the Warrior to “Auto

    Explore” and find

    “Goody Huts” (which give you free bonuses such as a Settler, or something else) is a great idea.

  • Thanks to automation, when a Worker is available, the player is able to automate the worker and let the artificial

    intelligence take

    control of it. The

    worker will then build the best available option on each square, as well as link your cities together by roads.
    This improves the pace of the game immensely and is a very efficient process, since you don’t have to worry about manually

    moving the worker (you

    can do that

    still, however).

  • Variety in food can improve your citizens moods making them happier. Entertainers are also available,

    spending tax dollars to

    buy their

    happiness and city improvements.

  • In total, there are 25 Civics options. There are five categories and five options per each category. The five

    categories are:


    Legal, Labor, Economy, and Religion. Some of the known Civics options are: Free Market, Environment, Slavery, Free Speech,



    Religious Tolerance and the Nationhood (it magnifies culture accumulation). Below is a table of how you will see your

    Government system in the

    game. Having all these choices means that you will not have "fixed" governments
    anymore (simply known as Democracy, Communism, etc in Civ3). Note
    that Civics choices have an upkeep cost (depending on the Civic).

    • Changing to new Civic forms will have a dramatic effect on the character and success of your civilization.

      You’ll be able to boost

      or cut
      productivity, wealth, and happiness, make choices to increase/decrease the spread of religion, and even affect your

      ability to produce and

      maintain a
      large standing army. It is also never as simple as choosing the only the
      highest levels in the Civics section. "…You could end up with a really

  • When you are at peace,
    Free Markets, Emancipation, and Representation are fine choices as Civic options. During war, you can select Civic choices

    which are

    better suited for that situation (which may mean that your units are not as expensive to maintain, and therefore you can

    have a larger army). Of

    course, to

    prevent you from switching back and fourth, there will be a temporary anarchy period between Civic choices if



A New Aspect: Religion

Church Art


religions in the game are equal. However they also have an impact on diplomacy.
"It’s like culture without borders," as Jesse Smith Puts it.

  • State Religions can be declared by any Civilization. You can also switch this, but you will go through a

    period of anarchy,

    just like when
    switching the state of your government. Declaring a State Religion means that all cities in the Civilization with the same

    religion get extra
    happiness and produce more gold. The default to no-state religion is Paganism,
    which means there is no organized religion.

  • Founding a Religion is done when a Civilization discovers a
    technology that is linked to a certain religion. Afterwards, a Holy City is
    established. When a Religion is established in a city, it will gradually spread from there.

    • When a City has a religion which

      differs from the State Religion of the Civilization, the citizens in that city may become unhappy and eager to
      adapt the state religion.

    • Since cities which are not in the Civilization’s state religion do not share the happiness and commerce bonus,

      it is a good strategy

      for you

      spread an unofficial religion. However, spreading too many religions to one Civilization is not always a wise tactic, The

      Freedom of Religion
      Civics option grants bonuses to civilizations which have many different religions.

    • You can see which State Religion of another Civilization you have made contact with by checking the small leader

      board in the


      corner of
      the game screen.

    • Like what has already been mentioned before in prior updates, the first Civilization to discover a
      technology that enables a religion will be
      assigned a Holy City. Owning a Holy City gives you a line of sight for all cities in the world that share that religion,

      and therefore

      you to spread to spread your faith even more around the world. In the Holy City you can also build Great Wonders that have

      the ability to improve
      the happiness of people throughout your empire. Holy Cities are assigned to the AI by random, but most likely near the

      center of the empire, or

      capitol of the empire.

  • Not only will you see Wonder Movies (CGI Cutscenes showing the construction of a wonder), but you will also

    see a movie each time

    you discover a religion. Winning the game also gives you a wonder movie (no matter how you chose to win it).

  • Every temple in the world dedicated to

    a religion
    will generate gold which will go to that religion’s Holy City. This makes it
    even more worth it to try and convert other cities around the world to your
    State Religion.

  • Conquered people who have a different religion than your state religion will naturally be pretty unhappy. In

    later eras you can


    technology to mitigate these effects, but religion now has to factor into your overall strategy.

  • Seven real-world Religions are available in the game. There is also a special unit
    for all Religions: the Missionary. Below is a helpful chart of the religions in the game, and their

    real-life significance:

    • The Missionary may be sent out to try to convert other cities to your religion. Just like Civics, AIs will try

      to convert you to their

      religion the same way.

    • If you are successful in a city, you will also receive a line of
      sight bonus and if you capture or control the main holy city of each
      religion, you get line of sights in each city in the world that has that

    • To keep your civilization’s religion strong, you must constantly be building religious buildings and pushing

      your own Missionaries to

      convert foreign cities. If you do not want foreign Missionaries to enter your lands, simply do not sign open borders.
      The only other time Missionaries can enter your borders are when a
      Civilization declares war on you.

    • While Closed Borders mean that other missionaries cannot enter your lands and spread their religion, it also

      means that you

      will not be able to trade with other Civilizations.

    • Success in spreading your State Religion to the AI will lead to
      better relations.

  • Religions will not have bonuses (most likely the developers like to keep everything perfectly balanced

    because it is a touchy

    subject), but

    they will impact diplomacy. If you ally yourself with a Civilization with the same religion as

    yours, it will enable
    you to curry favor with other like-minded peoples. However, they come
    with a memory, if you suddenly switch to their religion, they will not
    be as inclined to cooperate with you. You will need to be in their
    religion for a significant amount of time.


The Influence of Great People

Great Merchant


People also add a great deal of variety to the game. Some offer extremely great benefits as we’ll cover below…

  • There are five categories of Great People:
    Great Artist, Great Merchantman, Great Prophet, Great Engineer, and Great Scientists. All of them have a movement of

    two, and are invisible

    to other

    units. These will probably

    be triggered by City performance, therefore, they cannot be built. Each will also have three to four benefits, including

    culture boost,
    (created by Great Scientists),

    Golden Ages (when having two different Great People), and free techs, as well as wonder construction and city output.
    Please look at the first chart below for more details on their ability and
    historic figure.

    • Great People are easier to get in

      Civilization IV, and they
      will also be the only way a player can spark a Golden Age other than by constructing a particular Great Wonder.
      (Please see the chart below for more information on what exactly is required
      for a Golden Age when having available Great People.)

    • A Golden Age means that you get a boost in production and happiness (a
      Golden Age also lasts for eight (8) turns). Again, you can also have multiple Golden Ages (each subsequent golden age

      require more Great People) unlike in Civilization

      III, where you were allowed only one.

  • You can get great leaders by specialized cities. You can customize each city to fit a specific purpose such

    as science or culture.


    engineers will allow you to rush production on a wonder,
    or other building and naturally, they may only be used once, so it shouldn’t come as a surprise.
    A Great Merchant may let you establish an extremely

    lucrative trade deal (meaning you will get a large boost in your treasury), or a
    Great Scientist will significantly boost your research
    or create an Academy. Look below in the chart for much more details on this.
    Also you may want to check out the Cities section for more information on

  • You can generate more “Great People” points
    by taking city population away from working the land and turning them into specialists. Also, certain civics choices are

    able to make your

    specialists more
    productive and that can also have a positive effect on your “Great People” point production.

    • For all but one (the Great Prophet), there are ancient and modern representations of the unit.

  • Great People can be turned into “Super Citizens” where they can give a city an ongoing bonus
    for a period of time, or they can be used to give your Civilization

    a large one-time bonus. Below is a detailed list of the Great People, how they can be used, and the historic figures they

    might represent:

    People… For more information on the other units, go here.


City Essentials

Cities are like the many hearts of your Civilization. If you take care of them, they are bound to take care of


  • Instead of shields, youll see hammers. The more you have, the
    faster you build units, buildings, etc. The amount you have is determined by
    the terrain, and improvements

    • There is some sort of Hammer/Beaker rollover (Hammers mean production,
      and Beakers mean Technology research as said before).

    • When viewing the City Screen, a bag of

      money = 5 gold,
      an anvil = 5 hammers, and a loaf of bread = 5 food.

  • City Specialists: The number of city specialists are limited.
    However, with the "Caste System" civic you may have unlimited city
    specialists. Even though specialists provide bonuses to your cities, they do
    consume food (just like unhappy citizens, which don’t provide any bonuses at
    all). The total number of specialists are five. They are: Scientists,
    Priests, Engineers, Merchants, Artists. Citizens are the ones who actually
    work on the land and give you benefits such as food, hammers, and

  • Drafting can occur with either spending gold, or city population.
    Naturally, this depends on your Civics choices and it will also create
    unhappiness if you do draft.

  • Before founding your first City, the User-Friendliness of the game will immediately highlight attractive tiles to

    establish your first

    city, and later on,

    other cities. This feature takes into account nearby resources, terrain features and the proximity to other


  • GameSpot says

    that “Once you’ve

    settled down into your

    first city, the game bends over backward to be user-friendly.” Your first task after building a city
    is to select a list of offered and available

    technologies. Some of these are recommended to you before choosing them (it is very possible to ignore these

    recommendations). After selecting

    what you want

    to research, you will have to select what you want your city to build. Two of the options are recommended (just like some

    of the Technology

    Choices are). The

    recommendations are, of course, sound choices. But again, you can feel free to follow your own path.

    • Founding a second city quickly can be immensely helpful in solidifying a lead against your
      neighbor or neighbors.

  • To get more culture, in addition to the slider already described, Entertainment Specialists also help with

    culture generation.

    Building still

    matter, but they will just serve as cultural multipliers than producers.

  • A single city can sometimes be found with more than one religion. This usually happens when a foreign Missionary

    establishes its own

    religion in a city with

    a different established religion.

  • One-Tile City

    are not guaranteed the nine-square territory when you first build a city
    in Civilization IV. You may find a city that owns only its base tile,

    and is completely engulfed in another Civilization’s borders. To the right is an
    example of this…

  • Cities do require a maintenance amount, and with
    each city that will increase (therefore one can’t just start building Settlers and Cities right away like crazy). Even

    though this is a

    significant change,

    ability to build very large empires is still there. The difference is that it requires more strategy to do so. As cities

    grow, they
    are able to sustain
    themselves better without putting too much weight on the overall economy. Naturally, using diplomacy, religion, trade

    networks, and improvements


    income (and that will help fight increasing maintenance costs).

    • Cities on the outer-most fringe of your empire will still build
      relatively quickly (as there is no corruption anymore). However their maintenance cost will be higher to
      compensate for that.

    • The game is more balanced towards not having as many cities. You
      will, however, still have a broad area. The focus is to have fewer but more specialized cities.
      Also note that there is no city limit. You may build as many as you wish
      however keep note of the previous comment in the last sentence.

    • The city
      maintenance cost puts pressure on rapidly expanding
      Civilizations, when rapid expansion might not be the best choice at the time. The AI will recognize this too, and they will

      not keep throwing


      towards your

  • Balancing out your priorities is the key. If you build cities too often, they will be very vulnerable.

    However, if you don’t build
    cities and expand fast enough, you will be left in the dust. Prioritizing between expansion, research, building military

    units, and
    improving your core cities is really essential. Reading the landscape for resources, and good city positions is also very

    Building cities on hills or on rivers will help them survive longer, and make them less vulnerable.

  • Civic improvements/buildings are shown off on the terrain, as
    well as wonders. Basically, everything that you build (other than units) is
    shown on the terrain near the city.

  • Buildings

  • Right-Clicking on a city will bring

    up contextual menus, which will show the player options such as build orders, and governor settings.
    Having said that, the city governor provides much more control over

    • Information in the city itself is much clearer as well, for the players who do wish to get a more detailed

      picture. Each improvement

      in the

      has the specific benefits it offers to the city itself. Contentment and culture are also present in more detail. This means

      that the player will

      longer have to keep looking through the Civilopedia for what certain buildings or aspects add to the game-play.

    • In order to simplify your building choice in cities, you are able to Shift-Click on a city in order to select what

      you want it to build,

      this even without entering the main city interface. It will all be on the main interface. You will also be able to set

      Build Queue orders so you


      select which things you want to build in a particular order (so if you select the Archer then Temple and then the Pyramids

      in this order,


      will automatically switch each time a unit/building is done).

    • Selecting multiple cities makes
      management even easier. Jesse Smith states in this Developer

      Interview at GameSpot that the goal is to make everything as easy for the player as possible. This allows the player to

      set the same building

      orders to a few cities at once. These features (the Build Queue and the city selection method) along with the flexibility

      of options from the


      Governor make managing cities extremely easy. There are six governor options
      which will make it easy for you to customize what you want from that city.
      Emphasize food, production, commerce, science, great people, and "Stop growth."
      These can be mixed, matched, etc, etc.

    • Setting common Rally Points to cities (or multiple
      cities via the Shift-Click method) is also possible. This allows units that have just been built to go to that selected

      spot automatically

      without the

      player’s input.

    • When entering the city menu itself, you will see that older-style
      text-based menus have all been replaced with graphical icons instead. The
      uppermost part of the screen includes Scientific Research (center), Income and
      current gold amount (left), and the date (right). Also in the upper part is the
      current production (units, buildings, etc), growth rate, City name, as well as
      the defensive bonus of the city (determined by improvements as well as culture),
      health status (healthy to unhealthy citizens) as well as happiness (happy to
      unhappy citizens, this also includes the reasons the citizens are happy or
      unhappy). The top-left includes Scientific Rate,
      Culture Rate (as well as the happiness it generates), and Tax Rate (these three
      are determined as a percentage). We also can see a Maintenance Cost. On the left
      side of the City Interface is a Trade Route Bonus display (these provide gold),
      as well as what your current Buildings are. Also visible is the percentage of
      your nationality and Culture rate per turn. The bottom part is the build queue
      (Units, Improvements, or Wonders — all represented as icons), the lower-right
      part are the City Governor options as well as the Mini-Map. The Right Side of the screen we can see the current city
      religion; Luxury, Strategic, and Food resources; the city specialists are also
      on the right side, as well as the Great People accumulation points. The middle,
      of course, is the City Display. The Circled tiles represent worked tiles by your
      citizens Since a
      picture can speak a thousand words, here is a perfect example of the city

    • Just moving the mouse over the city will

      produce results such as how fast the city is growing, building status, resources collected, as well as culture and Great



  • No longer will you be able to transfer production from one project
    to another. This exploit has remained for a long time, and it has been addressed.

    • An example of the above bullet point is that when you lose a wonder to
      another Civilization by a few turns, you will also lose all the production made on it, therefore you will no longer be able

      to transfer it to

      another project

      however you will be
      refunded a certain amount of gold. This rule is for units and other buildings as well. For example, if you switch

      production from a Settler to an

      Archer, the

      production will
      not shift to the Archer, however it will be saved for the Settler when you come back to it, and you will pick up from where

      you left


    • If someone beats you to a World Wonder, you will get a refund, mot likely in the hundreds of gold, depending on how

      much time you’ve spent

      on that wonder.
      This has been mentioned just above.

      This (the fact that you can no longer simply transfer production) makes it much harder for you to “monopolize” the Great

      Wonders. This is even

      more evident

      on the harder levels.

  • Cities will no longer riot, but unhappy workers will not work. Until you address the problem, it will remain


  • City names can also be changed by the player, as in Civ3.

  • The bigger your city gets, the unhealthier it becomes. And
    that can take a toll on the population, as the city will eventually begin to starve
    (unhealthy citizens are not able to do as much work). You can combat this by building certain types of buildings, such


    aqueducts and
    hospitals. However improvements such as Factories tend to decrease the city’s health status.


Building Options

Strategy comes to play even more here… there are a total of 102 buildings, and each has its own benefits. It is up

to you to be the



Wonders of the World

Even greater buildings, however, are the ones which build up your civilization as a culture, and put it along other

major powers: The

Wonders of

the World

  • In total, there are about 28 Great Wonders (Great Wonders may
    be built by only one Civilization), and about 12 Small Wonders (every Civilization

    is allowed to build these, and they are more city-specific. For example, a
    benefit of +100% science.

    • On top of that, what makes Wonders so exciting is the fact that Wonder Movies are back! Each time you build a

      wonder, you will be viewing


      short clip of it. There are around 45 movies in all.

Your Advances

It is not the technology that matters It is how well you use it.

  • The Technology Tree, just like its technologies, is smart and flexible. You will have the ability to research

    different things, but

    they will

    lead to the same level of technologies. It will offer unique paths to guide your empire along. There are no longer static

    eras, as in
    Civilization III

    case, that is, the tech tree is not split into eras at all (although, as
    previously said, you can start in different eras). To put it simply, eras do
    not restrict your Technology choices and progress.

    • Like buildings, the player is able to switch
      from one technology to another, however that research will not get accumulated for the new technology you are switching to
      (in "Beakers," the accumulation of technology. It is similar to "Hammers" when
      talking about production). And when you switch to the technology
      you were originally researching, you will get back where you left off. However this “banking” of resources or research is

      limited in terms that

      you will

      start to lose production or research slowly over time. This change (production not carrying over to new buildings or

      technologies) has not been a


      balance issue
      because both the AI and Human Players are “on a level playing field” (to quote Barry).

    • There are different ways to discover technologies, like the already
      mentioned Great People and Goody Huts.

    • You will also be allowed to skip whole branches of the Tech-Tree if you wish.

    • The direction of your research will have an impact on the kind of Great People that are born. The player is free to

      choose any path

      whether it

      be all-military,
      all cultural, all-science, balanced, etc. You also dont need all the techs that connect to the one you want. A

      connection to it is all that



  • Even with evenly spaced-out resources it can
    happen that in the early game a player may not always have a resource such as iron or horses. The tech-tree also balances

    that out should it

    happen. It makes

    easy for the player to switch strategies and head in the direction of Gunpowder (for example).

  • There is no longer a minimum amount of turns in
    which you can discover a technology (in Civ3 it was four turns minimum). This makes it easier to come back and get

    older technologies you

    have not yet

  • There are 125 paths to Civ4‘s
    Future Technology.
    This information has been gathered from grumbler’s post here in the forums.
    Check it out for more information.

  • Below are all 86 technologies in the game. This technology tree
    has been put together by CivFanatics’ Administrator, Thunderfall (taken from
    several separate screenshots). Below it are details of what each technology
    has to offer:

  • Future Technology research gives you extra health and happiness, as described above. In

    Civ3 it is important to know that Future

    Technology did not do much for the player, and it is nice that that has improved as well.

  • Every time a Technology is researched, the grandfatherly voice of Leonard Nimoy (Mr. Spock himself!) kicks in with

    an appropriate quote

    from history.


The Military Backbone: Units

There are many different types of units, and all have different abilities. On top of that, there are special

promotions as well. This makes


military unit unique.

  • Civilization IV will ship with a total of 83 units (this
    includes barbarian animal units, which the player cannot build in a regular
    unedited [via the World Builder] game. This includes domestic units such as workers, military ones (of course)

    and special units such as Great People.

  • Units can be upgraded by using your gold, as
    they become outdated. This is similar to the Civilization III way.

  • Unique combat animations are a priority,
    so you won’t see the same old animation for different types of units.

    • Units will also give verbal confirmation when you select them
      and give them orders, again, this will be a specific language to the
      Civilization that is chosen.

    • When a unit is victorious, a short music clip plays confirming
      the victory.

  • There are
    on top of flags units are carrying to indicate how many units are in that tile. If there are 15 units in a

    single tile, there will

    be 15
    Medallions above the flag on that tile.

  • Medallions

  • Picking units out of a stack is easy so the player won’t have to repeat the picking out of a unit many

    different times


  • The longer a unit stays fortified, the more advantage it will have when defending against other units. For

    example, being fortified

    for five

    turns gives the unit its maximum defense bonus of 25%. The unit does not get an instant bonus the moment it is


  • "First Strike" is a system which simulates the advantages of
    ranged units such as archers. If a unit has this ability, it can make a
    "First Strike" against another unit before the combat actually begins,
    giving it an advantage.

  • Workers, when captured from another Civilization, build at the
    same rate as your own workers. There is no "half-normal" effectiveness as
    was the case with Civ3.

  • The game will also be using multi-unit graphics for individual units, they will also be carrying banners for

    their countrys flag

    and for


    identification. The Multi-Units represent actual hit-points. If you do not like
    to see multi units, you can turn this feature off so you see single-graphic
    units only. Below is a table of all known facts about units:

  • A nuclear explosion can cause severe damage to the tile targeted and the eight adjacent tiles. You are not able to

    attack your own

    territory or cities with the ICBM. Everything goes through a “kill check” (buildings, units and terrain improvements).

    Buildings are either

    destroyed or come out unharmed if they pass. Units can be destroyed if the “kill check” fails or damaged or unharmed if

    they pass. Wonders, roads

    and railroads are not affected by a nuclear strike. In addition to these potential damages, radioactive fallout must be

    cleared by workers when

    the Ecology technology is researched. Otherwise the affected tiles are unworkable.

  • Each time a nuke is used, the attitude of a Civ nuked goes down by 2 points (read more).

    Your relationship with

    other Civilizations around the world will also be negatively affected.

  • The UN Nuclear Non-Proliferation Treaty bans the construction and use of all nuclear weapons, but existing nukes do

    not disappear. If this

    resolution passes before the Manhattan Project is complete, you will not even be able to finish that project and therefore

    no nuclear weapons

    will be built or used throughout that game.

  • You can, of course, defend yourself from nukes by building the SDI Project which has a 75% chance of intercepting

    enemy nuclear weapons

    throughout your territory. You may also build a Bomb Shelter in cities. This reduces damage from ICBMs by 75%. Without the

    Bomb Shelter, the

    City’s population can be reduced as much as 50% by a single ICBM.


A New Combat System

How will you wage war? What new systems are involved? This is the section for the warmonger.

  • Spearman

    battle system is something that has been ameliorated (it is like an RTS
    "rock-paper-scissors" concept). It has been made to actually encourage players to use the array of forces they


    Players are able to group units, as an interface change. For example, you can group a Settler and


    Spearman, and they will always be together (unless you
    decide to re-group). Workers can be grouped together as well, and then their actions
    within that group can be queued. This has been changed so you will favor most different units, and not stick to your

    most powerful, for instance.

    • Using mixed attacks such as ground and aerial bombardments and not just on a single overwhelming stack of units

      (commonly known as the Stack of Doom) is highly encouraged. This brings more strategy to battles, and also makes them

      more realistic.

    • The fact that
      Artillery can attack all units in a stack forces players to spread out their forces to avoid damaging more units
      (artillery units can damage all units in a tile because of the collateral
      damage feature they have). Note that Artillery units such as catapults attack
      like normal units, although they can bombard cities and reduce their defenses.

    • The terrain also takes a large part in Combat. However, it can also be said that it is more simplified.
      The only time you will get a defensive bonus is when over hills, forests, or

  • Great Artists may also have a military-related use to them. If you capture a city and it is rioting,

    dropping a Great Artist and

    giving the

    city a 1,000 point culture boost
    should quickly suppress all rioting and change the mood of the citizens in the city. The only way you could
    suppress rioting in Civ3 was to basically start building a lot of cultural buildings such as Temples and


  • Selecting any or all units in a given square has many shortcuts to
    it. The game determines the best attacker when you give a

    stack attack order or the best defender when your stack is attacked.

    • Stack attack works by stacking a bunch of units and giving them
      the attack command. If you are using combined arms in that stack (a balance of defensive and offensive units), the game

      will automatically look

      at who you

      are attacking
      and who their defenders are.

    • The amount of damage a unit does to another unit is now
      out of a scale of 100, even though that’s more or less hidden from the user. The amount of damage a unit does is relative

      to its different

      strengths. So now

      when a
      spearman attacks a tank, he may hit three times, but that’s only going to take off a quarter of the tank’s hit points.

      Meanwhile, a tank hitting

      a spearman

      only has to hit
      him once or twice, and he’s gone entirely.

    • To further explain the combat system: Two units of
      the same relative power will do about 20% damage per hit, so it would take five hits to kill a unit. When one unit is much

      more powerful (a tank


      example), the
      more powerful unit does a higher percentage of damage than the less powerful one (a Spearman for instance). In other words,

      if both manage to hit

      three times

      in a
      battle, the Spearman would have done only around 40% damage, while the more tank would have already killed the spearman.

      However that is not all

      to the

      system. Many more calculations are going on behind the scenes that make for fewer lucky strikes, which further balance the


  • In the options screen, players can turn on an option
    that will let them see bars over units so they can judge their chances of winning or losing before even entering the


  • In all, Civ4 will offer about 41 different promotions for
    units (with 20 different promotion types. However some have more than one
    level, as you will see below. Units may receive up to 20 promotions as well). This allows each unit to be extremely

    flexible in its

    abilities. So,

    how do units get these promotions? Well, they might get them from a battle, depending on how difficult it has been. The

    great thing about

    promotions is

    that they are not triggered by technology either. As they win, they will gather experience points.

    You will make specialized units without changing any of their previous
    specializations; you can also change their paths with certain

    • Auto Promoting units is also an option you have. However you can always promote them manually.

    • The numbers and types of available bonuses
      differ per unit type and only land and sea military units can acquire them (air units are different).

    • There are no XPs (experience points) from bombarding
      fortifications or if the opposing unit withdraws.

    • Units can also gain experience from a Barracks
      (land units), a Drydock (sea units) or a goody hut.

    • Some wonders, civic choices, and leader traits can
      give units extra experience or even certain promotions. As you might expect, the first promotion comes rather quickly,

      while each subsequent


      requires more
      XP. Here are the different types of promotions and their abilities below:

      Promotion Benefit to Unit
      Amphibious Gives no penalty when attacking across a river

  • Some Units might also have an invisible characteristic. Great People
    (and possibly spies) are an example of this.

  • Infantry will have defensive bonuses in difficult terrain, while cavalry will have an advantage attacking

    ranged units such as


    Artillery/Siege units are stronger and will allow for damaging all of the units in a stack. Bombardment units are now like

    a hybrid of previous

    games. The damage a unit has is relative to their strength. Again, these changes were done to encourage use of combined


  • There are no longer separate attack or defense bonuses such as in Civ3. They will have only one base

    strength that might or

    might not

    increase or decrease. Units also have advantages or disadvantages against certain units. Pikemen will have a decided

    advantage over mounted units


    Axmen are especially good against melee units.

    • Units strength is represented by the number of units. At full strength, a unit will have three units, and when it

      takes damage it loses a

      single unit until it is destroyed.

  • Armies have been eliminated (in Civ3 terms, now they will only serve as moving of units together), but

    more customization


    countering is available in return as describe above.

  • Surrounding and isolating a foreign city with your forces is now
    a new strategy. This puts pressure on the foreign leader and he might

    eventually offer it to you via diplomacy. If he or she does not want to trade the city to you, the city itself has a good

    chance to riot because


    city’s population would want to join your Civilization.

  • You can
    blockade cities,
    for example, by moving your naval units close to an enemy city (that means that city can no longer

    work its water tiles).


    resources can also be harvested (this has been known for a long time). If you’re getting all your
    Oil from the water, you are in trouble because another Civ can cut off your oil supply, unless

    you can do something about it and defend your weak points.

  • The infamous "Spearman defeats Tank" phenomenon is now gone,
    needless to say.  This has caused a lot of headaches

    for Civ fans in the past. This will mean that units that are inferior will not be able to win against more modern


  • Early on the best city defense unit is

    no longer the Spearman, it is the Archer. Spearmen are more useful against other Cavalry units.
    Warriors are the weakest unit, however they are perfect for escorting Settlers and/or workers through danger zones (filled

    with wild
    animals as well as Barbarians).


The Multiplayer

Some people, of course, like to play with others online. How the multiplayer mode seems so far is promising.

  • This time, Civilization IV will have an integrated multiplayer so you won’t have to wait for expansion

    packs like we did

    with the
    series. A new co-op feature allows for more satisfying game-play than before when playing with other people,

    as you will form

    alliances against

    the AI, or other opponents. The map generator ensures that everyone starts equally as well, as the map is generated

    randomly. Player in MP will

    also be

    able to form
    permanent or temporary alliances with one or more players. Every game starts
    out with the server host picking rules, players picking factions (and sides
    if applicable) and then entering the game.

  • Youll be able to play a very quick online game with a friend or

    play long, ruthless campaigns lasting months. In MP, you can start out early, and end up playing well into the modern age,

    something which was

    difficult to achieve with Civ3s MP. In MP, there are five speed
    settings: Blazing, Fast, Normal, Slow, and Snail.

    • Even though, through PitBoss, players

      can play as long as they like, there is a mode which also lets players to play shorter games (100
      turns, from the Stone Age to the Bronze Age for example).

  • Right out of the box Civ4 supports up to 18
    players online. This allows basically every Civilization to be played.

  • Players are able to compete in traditional turn-based or simultaneous move games either on a network or via

    the Internet.

  • If and when a player or players are disconnected from the game, a screen (labeled “Democracy”)
    pops-up giving the other players still in the game to vote on what to do. The options are: Kick the player out of the game

    and replace his

    Civilization with

    an AI player,
    save the game and continue playing until the player can join back, or just wait for the player to re-connect and proceed

    with the ongoing game.

    Games are

    easy to save, even if the circumstances are not so bright.

  • Team Play: Players can form alliances with each other in multiplayer games. Allied nations will put their

    accomplishments together,

    join forces

    in combat and share all information, even line of sight, benefits of wonders, research (two players, for example, can

    research one thing at the


    time to discover it faster), unit trading, and sharing of territory. These additions deliver a plethora of new strategic

    and tactical options to


    players. Team-Play is available both in MP and SP (Single Player) modes.

    • In Multiplayer, the server browser will include buddy list
      functionality to keep track of friends easier.

    • Timers are set in Multiplayer in order to make everything
      move smoothly (and so people can’t stand there doing nothing for a longer time).

    • Missionaries are very valuable in
      Multiplayer. It’s even possible to force another civilization to adopt your religion, which can potentially bring in a tidy

      sum of money for you.


      can become very unhappy
      should their way of life change so dramatically, however.

  • Teams can

    easily communicate with each other. Example: You are able to put signs
    on tiles and draw lines on the terrain and other players are able to see that and know where to go

    (if a specific location is your goal. This is available in Single-Player mode as
    well). Players can even send little pings to alert teammates of important events happening around their map. Support for

    voice over IP also allows players to talk while playing.

  • You can go in and protect your ally’s cities unlike in Civ3.

  • There is also a new “Double City Elimination”

    in Multiplayer which means that if you lose two cities, you lose the game. To go
    into more detail, there are different modes of it. If you take one city it can
    instantly burn to the ground, and therefore you are at an instant advantage.
    You can also set it so the city does not get razed, and if your opponent takes
    back that city, the score is leveled out. The “One City Challenge” option means that you can have only one city. There


    the “Always War” and “Always Peace” options as well. For a game, you can chose one or the other (you are, obviously, unable

    to select both at the

    same time).

    These features can be mixed to create the MP game you want.

  • A particularly hardcore game can be created

    by playing with teams and handicaps. With two teams (one with one person, set the level to the easiest difficulty so that

    player gets a bonus on

    most all

    areas of game-play) and one with several other people on a normal, or harder difficulty for a greater challenge.

  • In addition to the standard internet, Hot Seat, and LAN modes, Civ4
    is playable by email (PBEM), or on a persistent turn-based

    server, or PTBS (named PitBoss).

    • The Pit Boss
      persistent turn-based server will allow for players to play as long as they like and leave when they like without

      disrupting the game. Players


      also fill in for AI players and join when they like
      (so it is possible to jump in right in the middle of a game and take an AI’s
      role). The server will download the current game state, then a player takes their turn and the server
      afterwards saves for the next player. It is like playing a streamlined version of play by e-mail or hot seat


    • The
      Multiplayer pit boss, which will allow persistent multiplayer games of Civ4,
      was released in December.

    • Firaxis will cull all sorts of statistics from multiplayer
      matches, which will let it rank players, which is aimed to avoid some of the frustration when you find yourself in a

      multiplayer match with

      ruthless Civ


  • Connectivity: From Jesse “Friedrich
    Psitalon” Fletcher’s MP article
    GameSpy NAT negotiation allows people behind routers, firewalls, etc, to
    play with no trouble at all – no opening or closing of ports, zones, etc. If
    needed, Direct IP still exists, and WOULD require playing with ports, but the
    only port you need to open is 2056, or whichever port you specify in your INI
    file. No more OOS. Except if you are playing a different version of the game.
    The game has even shown the ability to "resynch" itself if a genuine
    problem arises temporarily (hotjoining players sometimes cause a 1 or 2 second

    is playing by the same rules (be it in a casual MP game, or

Customization Flexibility

People do not lie when they tell you some like to customize the game just as much, or even more so than to actually

play it. What’s new


View Section Notes

  • Civilization IV will set a new standard for user-modification allowing gamers to create their own

    add-ons using Python and

    XML. It
    is the most customizable version of Civ to date! Basically, full mod support is offered here, and almost nothing

    in the game is


    (unlike in Civilization III. Firaxis has also said that a fully customizable Government system

    will also be


    among the many other things…Below are the four modding levels Firaxis games has released information on, ranging from the

    easiest (the Map


    to the most difficult (the Software Developer’s Kit).

  • In-Game Editor ShotMap Editor: This will probably be like the Civ3 Map Editor. It is the easiest way to mod the game your

    way, and yes, anyone

    at all can

    do it

    with ease. Just open the editor and you’ll see the ability for you to tweak and change everything from Cities,

    Technologies, Units, and

    Diplomacy. For cities, you

    are able to add a specific population number (as the screenshot to the left illustrates), culture points, gold amounts and

    even change that

    city’s religion.

    Adding technologies to the ones you already have is also possible. For units, you are able to change the level and

    promotion type of any

    available unit as

    well. Changing the terrain type is also another distinct possibility. Just like you are able to edit Technologies, Cities,

    and Units for your own

    Civilization, you are given the option to change these same aspects for the other available Civilizations in the game just

    as easily. The World

    Builder even

    goes as far as letting you change diplomatic options and relations. The editor also opens the way for cheating.

    Quoted from CivFanatics’ Hands-On preview. The World Builder can be

    launched at any time during a game so players can add new cities as well as creating new starting conditions. The created

    maps are stored in a

    text-based format, which can

    be opened in a text editor. What this does is basically make it easy for you to edit without even starting the


  • The Flexible XML (eXtensible Markup Language) Files: All values of the data for the aspects

    of the game such as

    units, terrain, texts,
    camera controls, graphics scales, mouse and keyboard mapping, links to
    Python, audio scripts, and so forth are stored here. Game

    speed will also be Moddable through the XML files. A perfect example of this is that a player can make

    some units get build


    fast, while making other improvements get built at a slower rate. There are lots of tutorials on the Web for this, so you

    may want to check out


    sections notes and get prepared for it if you are enthusiastic about modding the game (as so many people are). Every art

    asset has a scale value

    is in

    XML, and it can be modified
    the way you like (these include buildings, trees, units, improvements, resources, etc).
    You can also modify terrain-specific movement just by doing a change in the
    XML file(s). An example is "Mountain Infantry". Also, through XML, players can add new unit or building

    types, change the cost of

    wonders, or add new civilizations. Players can also change the sounds played

    at certain times or edit the play list for your soundtrack. NOTE: You can have custom soundtracks simply by adding music to

    the custom folder.

    You only need

    to edit the XML in order to assign certain pieces to specific eras or remove certain pieces.

  • Python: Moving up to a more difficult modding level for most players, Python is a very powerful scripting

    language that will allow


    familiar with the scripting language to do things from changing and totally reorganizing the interface (as all of the

    interface is written in


    to changing more algorithmic parts of the game like map generation, combat, triggers/events
    (there are, by the way, around 30 triggers including new unit, building, end
    turn, unit move, etc), and even the AI.
    A Python interpreter is also added to the game which makes it possible for
    the player to open it during a game and generate code "on the fly" or check
    other variables. Players will now have the ability to add scripted events to the game like automatically

    generating units when a tile is reached, having specific situations trigger automatic war, or get this, bringing back Civil

    Wars caused by

    unrest, Civ II


  • AI Software Developers Kit (or SDK): For even more advanced modders, Firaxis is offering the entire AI and

    Game Code of the game.



    can change literally everything about the game they want. They can even create and write their own game types to pretty

    much building their own


    loosely based on Civilization. Literally everything can be changed
    (including the camera position). It has been said that it is very, vary rare for such an amazing modding

    level to be released for a strategy game. The AI SDK will be available shortly after the game ships,
    in early 2006. Modders can do anything short of changing the basic graphics engine, the core Civ engine, or

    the network code.

  • Some new modding tools are the: Unit Formation
    Editor (this gives control of where units stand on a tile, how many units are in
    a formation, and under what situations a certain formation is used), Hot-Swapping of Assets (meaning that the computer

    detects any changes
    and can load them "on the fly"), Python Scripting for the World Builder,
    Python Interpreter Console, Python Editable UI, L-System (Lindenmayer System) City Building
    (which makes the city graphics look random with each build, but it is also
    used to generate terrain features such as trees),
    Colored Map Overlays… The GameCore DLL is a "Pluggable Module," which
    will make no assumptions about the underlying platform and hardware,
    [and more].

  • The new Bitmap Converter lets you import BMP files and turn those into
    Civ maps, letting you download a topographical map (or a picture of your
    favorite celebrity) and have the game extract sea levels, mountain ranges and
    other information straight from it. Giving the Bitmap Converter any BMP image
    and it will make a Civilization IV map from it. Everything blue becomes water, everything green becomes grass – with

    the proper image even

    entire mountain formations can be achieved
    (fives images: Terrain type, plot type (mountain, hills, flat, water), rivers,
    features (jungle, forest) and resources..
    This tool is already available. Click here to download it (it

    did not ship with
    the game).

  • A debugging mode is included, so you can switch off the FoW (otherwise known as the “Fog of War”) and watch how the

    AI behaves and


  • A number of pre-built scenarios will also be available with the
    game as it ships that also have different victory conditions. The World War II scenario, for example, will start you with

    all your cities and

    military units

    already built,
    and instead of conquering the whole world, you may have a more focused goal, such as taking or defending Paris.
    There will also be a World-Map included. An American Revolution scenario will be included in the game as well. Here is a

    screenshot of it.
    Greek World, Earth 1000 AD and Desert War are also some scenarios which have
    been included in the game.

    • Even more Scenarios and a really top-notch tutorial (to help new players out) will also be included in
      . There is also no doubt that

      with the presented modding abilities, we will see some very exciting creations from all corners of the Civ
