http://freeciv.orgis a free turn-based multiplayer strategy game, in which each player becomes the leader of a civilization, fighting to obtain the ultimate goal:
To become the greatest civilization.
Players of the Civilization® series by Microprose® should feel at home, since one aim of Freeciv is to have optional modes (called rulesets) with compatible rules.
Freeciv is maintained by an international team of coders and enthusiasts, and is easily one of the most fun and addictive network games out there!
That also means it has very extensive multilanguage support, something rare in games.
This is a screenshot of the SDL version. Click for full size.
I have compiled both the SDL and GTK version of this game.
The SDL version is slightly buggy in places (such as going back in the menu at the beginning) and is hard to use if not in fullscreen, but has many more GUI aspects such as buttons for movement and building.
The GTK version is slightly smaller, less buggy but has a slightly less nice GUI. There are still menu options for building things, but it is much easier to learn the hotkeys.
You cannot have both versions installed at the same time - they will overlap. Requires SDL (click here.)
