Most to Least played:
Trem 1.1 (1.1 > gpp)
Trem GPP
Unvanquished (1.1 > unv > gpp, rota probably might take advantage of this)
Xonotic 0.5 (bah, too many good aussies, not enough noobs)
Quake 3 (with CPM physics) 1.4 (or something like that)
Team Fortress 2 (feels really slow with these fast-paced shooters that I play)
Q3 Defrag (basically quake racing around the place through strafe jumping and shit)
Uberstrike (a rip-off off q3 + COD on unity 3d engine, dunno why i'm addicted to it despite the game being so shit, got a k/d ratio of like 22.5 something despite being a total newbie to this game)
Soon to (re)install:

Just Uninstalled:
Planetside 2 (can't run on my computer, everything is green with drugs, and 2 fps)
