I'm pretty much good at anything except racing, fighting, and most FPS games. Like I'm pretty bad at Smash Bros, and the only FPS I was decent at was Modern Warfare 2, and I've sucked at every racing game post-Mario Kart 64. Though I'm freaking awesome at Star Fox/SF 64, that's probably the only shooting related game I'm great at.
I normally excel at RPGs, puzzle games, strategy games, and platformers. Probably because they're the only ones I'm typically ever interested in playing.
