I consider Alpha Centauri to be the sequel to the Civilization games since it starts after the spaceship launch. And this is one of those sequels who put their originals to shame. I still think it is far better than all of the Civilizations put together. The configurable units, the awesome setting and the Datalinks archive that makes for one of the most quotable games I have ever had the pleasure of playing. If you even kind of like turn-based management strategy games, you have got to buy this.
