2D platformers, believe it or not.
I like a lot of them, finished most I played and the original Yoshi's Island is in my top 10 favorite games of all time, but I'm really bad at them. Even on NSMB, which is supposedly easy, I die like a billion times, let alone a hard one like Donkey Kong. 3D platformers feel much more natural to me and thus am way better at them.
I'm rusty at some other genres, but that's mostly because I don't play them very often anymore. These are FPS's, rhythm games and fighting games mostly, but I used to be skilled enough at Call of Duty, was quite decent on SoulCalibur and was excellent at Guitar Hero so I know I'm perfectly fine at those when I put some effort in it.
