I'm pretty garbage at online FPS, but I attribute that to not really liking online FPS' whereas other people seem to fricking live in them. It's a bit like a guy that just got out of the swim class showing up to the 400m Medley at the Olympics asking if it's cool if he just tries a bit. The games that I really and truely suck at and despise wholeheartedly are racing sims. I'm actually pretty good at arcade racers (Motorstorm FTW, Old school Ridge Racer was bomb too) but damn, Gran Turismo and it's ilk can pretty much blow me.
