Those who missed out on Firaxis and 2K Games' Sid Meier's Civilization IV the first time around will be getting another chance to get their copies of the game. Not only the base Civilization IV game, mind you, but also the game's three expansion packs.
All that will be in the newly-announced compilation, Civilization IV: The Complete Edition. For US 39.99, you get Civilization IV and the Warlords, Beyond the Sword, and Colonization expansion packs. Press release also mentions that the compilation will be DRM-free, so yay!
Civilization IV: The Complete Edition will be available in North America on May 12.
