i think that they're all great, and that yoshis story was a good straying from the mario concept, but i feel that mario 64 was THE mario game. it pushed graphics and gameplay where they werent beefore, and it was a great game. not to say that the other mario's werent (except mario rpg imo-terrible), but mario 64 set the standards for all future games and hopefully mario sunshine will be good as it looks like it's using the same basics
