Do you people out there recommend some PC games? don't include this, i already have them: MW2, Black Ops, Bad Company 2, cs source, Just Cause 2, Crysis 2.
seeing the games you posted, i'm guessing you have a nice rig. but still, it doesn't hurt to post your pc specs. other games i'd recommend you would be the witcher 2, assassins creed series etc. also you seem to in fps games huh?
If you're into First Person Shooter (FPS) which seems so from the games you've posted, you should try the Half Life 2 series. Epic!
Btw, you could narrow down your gaming genre...RPG, RTS, MMO.
