Galaxies is a great game and it definitely improves on Sunshine graphically. My only complaint with Galaxies is the fact that it presents no real challenge... its very very easy. Sunshine, and 64 for that matter, seems to be a lot more challenging and therefore more rewarding. But don't get me wrong, I still love Galaxies and plan on getting every single star and unlockable possible and enjoying every minute of it, just like in the last few mario games.
