My control aspect. While holding a steering wheel in the air to steer with is a neat gimick, it really doesn't give you quite the same level of control and ends up being more frustrating than fun in the long run. Playing with the standard Wii controller is ok but it's really just not as good as using the GameCube controller. So my dislike comes from the controllers available by default more than anything else. Also, since the Gamecube version was the first one i played, I got used to having two characters and switching back and forth between them. The Wii version goes back to having only a single driver.
