MichaelFurlong: TLDR; A variation on the civilization games allowing the player to explore future technology such as mechs and aquatic cities. Nothing fundamentally new but offers a new twist on the basic civilization game.
Call to power (CTP2) 2 was released before Civ 3, and shares the same basic gameplay of a Civ2/3 game, so if you don't like civilization you likely won't want to play CTP2. CTP2's major difference is that it deviates from Civilization's technological realism and allows you to play and research many years into the future with mechs, hover tanks, A.I. and aquatic cities.
If you like the basic Civilisation gameplay but find it becomes repetetive and want a bit of variation in the gameplay now and again then I would reccomend buying call to power (and alpha centauri).
I personally own CTP2, alpha centauri and Civ 4, and I switch between the games otherwise I get bored.
I won't bother going into detail with the basic game mechanics as they are more or less the same as civilization 2/3 however it does have some noticeable differing features. The graphics are midway between civ 2 and civ 3, probably closer to civ 3.
