Star Wars Galaxies
Jedi Knight 2
Quake 3 Arena
Return to Castle Wolfenstein
Neverwinter Nights (just bought but prolly wont play for a couple weeks)
I also just borrowed all my DAD'S Command and Conquer games (he has every one from Red Alert to Generals). He is 52, doesn't know anything about computers or how to fix any problems, but he can whoop anyone at C&C Generals.
