- Quake 1 (standard installation)
- Quake 2
- (soon Quake 3 Arena)
- Half-Life (Counterstrike, Team Fortress 1.5, Action-HL)
- Jedi Knight 2 (not installed)
- Jedi Outcast
- Unreal Tournament
- (soon Unreal Tournament 2003 [this evening?])
- Max Payne, Operation Flashpoint...
I should add that I'm not really good in most of the multiplayer games, except for Team Fortress. I think I'll have to resize my games-partition before I can install new games.
