Most advanced strategy game what have ever been built. Simple as that. Sid Meier's Alpha Centauri (sometimes abbreviated to SMAC or Alpha Centauri) is a turn-based strategic computer game created by Brian Reynolds and Sid Meier under the auspices of Firaxis Games in 1999. It is based on a fictional attempt by human beings to colonize a planet in the Alpha Centauri star system. It picks up where Meier and Reynolds' earlier titles, Civilization I and Civilization II, left off. It is way more complicated than any civilization series game have ever been. That's why it is the best game in the world.
