Galaxy: Best Mario since Super Mario Bros. 3
Suits are back: One of my favorite thing in Mario 3 has finally returned. However I wish the brought back the froggy suit for water levels. They are fun. Especially the Bee suit it's really cool sometime I would just fly around and do nothing then look at the levels.
Classic Music:
A lot of great past tunes were brought back to the seris. All remind me of being young and killing koopas.
Camera:
Actually follows you nicely, this was a huge relief because it made the 64 version miserible. It's still not perfect though.
Just plain fun:
This game is really hard to put down even after several hours of paly because you just have fun playing it. Please, Just go buy it already!
