So, I have a mid range G5 Tower, and I want to know, if there are any free open source games out there? I am aware I could just go buy some Mac games, but that'd be kinda pointless to buy versions of games I already have on PC lol.
Wolfenstein Enemy Territory HAS to be the best free game I have ever played. However it has a lot of compatibility issues on the internet nowadays (sadly). If you play on making a LAN party, I urge you to get it though!
If your computer is powerful enough, get Nexuiz, good 2009 open source quake-like.
