Freeciv

Free Civ is one of the best Linux Games. It helps to relax, after hard coding =)

Very interesting and useful game for brain =)

A Great game. Respect to Sid, who made the original Civilization, and to all the guys who support Freeciv.
After playing for a while, i decided to participate in localizing it to my native language, and that is no less interesting than playing.

freeciv is really old now, and the graphics, ergonomy should be revisited. There is also a lot of micro-management in the game.

However, it can still be pretty addictive.
