C-evo

C-evo is a free turn-based strategy computer game whose source code is in the public domain by German programmer and designer Steffen Gerlach. It was written in Delphi and later ported to Lazarus instead.

C-evo is an empire building game based on Civilization II, but with a different focus; it aims to be a pure "game" with all players playing to win, rather than the more simulationist side of the Civilization series. As a result, it is known for tough and uncompromising artificial intelligence computer opponents; some of these AIs have been contributed by the player base and are separately downloadable.
