Keeps the series going better than ever.
It has all the things you'ld expect from a mario game (keeping 64 and sunshine in mind) plus it takes you to a ride of your live.
It already begins in the first (real stage) : the good egg galaxy : it let you experience walking on a small planet where the gravity is everywhere , you won't fall of.There are a lot of those planetmix galaxies in this game.
Next are the solid galaxies with only one big planet and maybe a small moon or two ( one of em my favorite : the beachbowl galaxy).In such galaxies it is a bit harder to progress, since you have to scout the planet for clues.And the last kind of galaxies are the one's with a boss.Not much about it , you land on a planet , you follow the trail and you defeat the boss (sounds easier then it is).Also mario moves great , he doesn't punch anymore but the spin attack compensate's it very well. The only bad thing is tthat it is not required to gather all the stars to get to tne endboss , but if you gather all the stars ( takes a while , take my word for it) you get a big surprise that makes it all worthwhile (in the beginning).
