It annoys me when people can't play games properly. They'll choose the damn hardest song on Expert (on guitar hero or rock band) and when it starts showing that they have no chance of winning they quit, it drives me insane. There the songs that I can do but don't like doing, as they hurt my hands ;[
It also drives me insane when people button bash on Soul Caliber and use the same move OVER AND OVER AGAIN. It's always that really annoying move that knocks you to the floor too, so you stand up and try to block or fight back and wham you're back on the floor again, repeated 9001 times till you KO. Where's the fun in that at all? f,mdsjfkdfdfklfgkghjj
