Its overrated as hell. And this is coming from a huge Mario fan. The jumping physics are garbage and totally stiff. The worlds are colorful, but not fun to explore. The level design is fine, but Mario Galaxy puts it to shame, and most of all, it doesn't feel fun to play. I feel as if I'm one of the only people around who really doesn't like Mario 64, but its clunkiness and lack of entertaining ideas and areas makes it a total drab, and I've not once really enjoyed it.
