I dislike mario kart because it has that system where the farther behind you are, the better items you get, where if you're in first place you get nothing but banana peals and green shells, why don't they make it fair where it's all random no matter what place you're in?
I like racing games where it's nothing but pure racing, so the luck factor is extremely minimal
EDIT: I also dislike how MKWii is just MotorCross, since bikes are clearly better and most of the race is popping wheelies and jump off of corners upwards of 50,000 times
