Call to power 2 takes the classic Sid Meier's game and gave it steroids. It is vastly superior in every way apart from a few aspects of the AI. So buy this game and couple that with the free Apolyton source code project mod which improves the AI and makes it more intelligent and fairer (no more unfair AI unit creation and building wonders of the world in 5 turns), together with GUI improvements and tons of new options to make the game bigger & micro-management easier, plus so many small improvements, and you have what I consider the best turn based Civ game-play ever. The only thing missing when comparing this to Sid's 1, 2 and 3 is the palace upgrades you get for a job will done. All in all if you loved Civ 1, 2 and 3 and you want some more of the same but so much better then you will love this game even more.
