Freeciv is a multiuser reimplementation for Unix/X of the famous Microprose game of Civilization. By default, the game is an improved Civ II, but this can be customized; modpacks for near-100% compatibility with Civ I and Civ II are included.

It is maintained by an international team of coders and enthusiasts, and is easily one of the most fun and addictive network games out there.
