i like WarRock its an online FPS like CSS but its FREE! unless you want more stuff of course
UT2004 is still awesome but i dont know if your computer could run Unreal Tournement 3
YES! it is 3 instead of 2007 because by the time they get it out there will only be a couple of months left of 2007 and since the new Unreal 3 engine came out they named it 3
