Anything involving motion controls. Any game with Square Enix on the box. Fighting games. Any sports games other than football or the occasional extreme sports type affair. Driving simulators like Gran Turismo. But arcade style racers are fine. MMO's Real time strategy games.
It's an honest answer. They haven't made anything that interests me in a long, LONG time. I can think of one Nintendo-published game that I liked: Eternal Darkness. I'm not saying other people can't enjoy what they produce, I'm simply saying that Nintendo's product hasn't interested me since the early 90s.
