Moved to UT as it required better hand-eye coordination then Quake series, Rainbow Six until it goes ruined by lazy devs (seriously it was the MOST tactical game... now its practicly UT!), Half-Life series, Tribes Series, Battlefield 1942 and Battlefield 2. Probably missing a whole lot of them here but basicly the hayday of FPS games was MY age... NOLF is one I almost forgot... until about 2000 I played every single FPS and a couple competitively like Tribes.
Up until the point where they started making FPS for the console games I was a heavy FPS user... but couldnt handle the limited gameplay so I stopped playing for a while. Now that the consoles dont limit the game so severly (Sorry Halo was trash compared to what was on the PC years before!) I am looking forward to making a jump back to online. Was in competitive OGL Clan for the Tribes series.
Some of the decent PC FPSs lately have been L4D/2 and Bioshock. Hoping Brink gives that pace that only a FPS on a pc can deliver and looking forward to Tribes Ascend, Battlefield 3 (maybe) and Bioshock Infinite.
