I hope you enjoy this scenario - feel free to distribute it, modify it, etc. Any suggestions or bugs can be sent to me at cscud1@mfs01.cc.monash.edu.au

I tried to make it historically accurate - the population of each power is exactly half the real population of the time (for example, Germany has a game population of 22.5 million versus a real population of 45 million at the time, etc.). The exception to this is Russia which only has a population of 50 million versus real population of 160 million, but I will comment on this later. I used such high populations to make the game realistic - now sieges can be used to cause famine in enemy cities, because the cities are usually rationing (i.e. no food surplus). Britain has an experimental armour unit (despite lacking Mobile Warfare), to represent the first use of tanks in warfare in 1915. Turkey has two battleships in Constantinople, to represent the Goeben and the Breslau, two German warships given to Turkey. Germany has some howitzer units on the Western Front (despite lacking Robotics), to represent the giant Krupp guns used to bombard Paris. The US has no units whatsoever to show that it is neutral and isolationist at the beginning of the war. Irish revolutionaries are shown as partisans, while Lawrence of Arabia's Arab troops are shown as dragoon units. Russias capital is at St. Petersburg, NOT Moscow, and many Russian cities have food shortages to reflect a famine at the time. Minor countries have been represented in three different ways: a) by being non-existent - Denmark, being hardly a crucial force during the war is ignored. b) by being a city of a major power, so Bulgaria (Germany's ally) is shown as a German city, while Greece, Serbia, and Britain's colonies are all shown as Allied cities. c) by being passive barbarians - Spain, Sweden and Norway are shown as barbarian cities. The major powers are at different stages of development, reflecting in part the difficulty level of leading certain countries. The most developed is the Allies, who have access to all forms of government and have extensive railroads, farmland, infrastructure and funds. Next comes Germany, which can choose most forms of government, and has extensive railroads, farmland, infrastructure and funds. Next come France and Austria, who can also choose most forms of government, have intermediate levels of railroad, farmland, infrastructure and funds. Next comes Italy, with limited government options, few railroads, some roads, farmland, infrastructure and mediocre funds. Finally come Turkey and Russia which can only attain despotism/monarchy (although Russia is researching Communism), have some roads and irrigation, and meagre funds. The African colonies, and minor powers all fall somewhere in between these categories. 

The reason I have given Russia only 50 million, and not 80 million (as would be implied), is - and this is a bug of the game I have not been able to solve - is that if you play Russia, you could easily obtain the Democracy, or the Republic, and you would (after a time) easily become invincible. All I can suggest is that if you play Russia, you avoid this temptation!, or if you play another power, you strip Russia of these technologies if the computer player (Russia) obtains either of them.
