From the README

Unofficial open-source OpenGL/SDL2 reimplementation of Sid Meier's Alpha Centauri ( + Alien Crossfire ).

Note: you will still need to own the original game and expansion - GLSMAC will load its resources like images or sounds.

Check Screenshots and Videos for current state and history of project.

SMAC was a great game, possibly the best in 4x genre, but it's outdated so much it barely runs on modern systems. Especially multiplayer (which is based on ancient directplay). Also it can't be modded as thoroughly as many would like.
