I've just notice that I'm just "good" at FPS games. I'm not amazing at them.
I'm like a beast at fighting games. I whoop everybody's ass at UFC Unleashed (2009 and 2010), Super Smash Brothers Brawl, Marvel Nemesis: Rise of the Imperfects, War of the Monsters, and pretty much every other fighting game that I play.
And I don't know if Prototype is considered a "fighting" game like UFC Unleashed or something is, but I'm a beast at that one too.
I have my people that I'm REALLY good at with fighting games too:
UFC Unleashed 2009 and 2010: Anderson "The Spider" Silva (the guy in my sig and avy, AKA the best fighter on the planet)
Marvel Nemesis: Spider-Man
War of the Monsters: That big gorilla thing (I think it's name is "Congar" or something)
Super Smash Brothers Brawl: I will beat you most of the time with just about anybody, but I will DESTROY you if I'm Diddy Kong.
