As a civ-fanatic you might, like us, live a bit in constant pain, because you simply cannot buy Civ1 and Civ2 anymore :(. The reasons are probably complicated, and related to a not-so-easy licensing situation after Microprose was bought. But as you know, you can buy Colonization on GOG, so it must be possible. If just Firaxis and 2K knew that we really wanted these two games, then they could probably do it.
One of our moderators, blake, has therefore organized a vote two get both games onto GOG. Show us, Firaxis, 2K and GOG that these games are still worth playing, and vote that they should be added. With some luck, in the future we might be able to play again those two games.
