AstroMenace 1.2 - Real Gaming in Linux

While changing to a great OS like Ubuntu , I had to make some sacrifices , one of them being : less gaming. I'm not seeing I ended my gamer " career" , buy i start to look for smaller web games , or testing the big LINUX games that everybody was talking about. ( Tremoulos,Quake Wars,Nexuiz,Battle For Wesnoth).
