Overall, I think this game is not nearly as most of the people who've reviewed it have made it out to be. I certainly don't think it defines any new ground in terms of platformers. 9.7, IGN? I think not.
Don't get me wrong - it's fun, about an 8-8.5. But motion is really awkward - particularly when you can't see yourself, though I guess I shouldn't be surprised that a 3-D Mario game has camera issues....
When they talked about "galaxies" in the game I thought they were talking about worlds, not little pieces of poop of which Mario is about 1% of the mass of the whole rock. No wonder the ground shakes when he does a stomp.
The Wii's motion-sensitive controller only goes so far - it's really too bad that there aren't really specific motions. Just "shake" and "point." Though, it certainly feels more natural that Super Paper Mario.
Seriously, I think Miyamoto has been taking estrogen. His games have become more and more childish over the years. WTF?
