The Humble Store has a number of Linux games: http://pcgamingwiki.com/wiki/Humble_Store http://pcgamingwiki.com/wiki/Humble_Store Sid Meier's Alpha Centauri is a favourite of mine, not sure how easy it is to get a copy of these days though. DEFCON, Darwinia: http://introversion.co.uk/ http://introversion.co.uk/ Wesnoth is a great turn-based strategy game and has an unusual amount of polish for a FOSS game. SpringRTS is a really fun RTS, if you can look past the many bugs in the launcher/lobby: http://springrts.com/ http://springrts.com/
