Don't mind him, this faggot got blown the fuck out in a Quake 2 thread after saying all console shooters sucked and his anus hasn't recovered yet.
Personally, I like WinQuake. It's easily the most dated and crusty version but I like the aesthetic and general "feeling" the best. If you got the game off gog.com
or whatever it comes with both WinQuake and GLQuake. Both are very faithful ports of the original DOS version.
