Sid Meier, one of the best designers in gaming industry in my opinion, has done it again. It's true that Alpha Centauri looks, feels and plays a lot like Civ games and that's the real beauty of it.
This is better than any of the Civ games, IMO. The only turn-based strategy on PC that competes with it is Master of Orion 2.
