i dont know. galaxy?

I tend to lean towards Super Mario Galaxy but really its so close that I could go either way with it! Both games were a lot of fun but I have yet to play through either game more than once! I'm taking Mario Galaxy's side because at least I got a few weeks out of that game getting every star with both Mario and Luigi but with NSMB I beat the game in 2 days and got all of the star coins/all the stars within 4 days of getting the game! Both games were a lot of fun and both were worthy 2D and 3D sequels!!

Mario Galaxy hands down. Can't wait for SMG2

NSMB Wii is the better game. I haven't played it yet but I know.

I loved SMG so much but after completing the bare minimum, I couldn't be bothered touching it ever again. That has never happened to me with 2d mario before so I know as soon as i buy NSMB Wii, it will be confirmed

I hated Super Mario World and loved Super Mario Wii. I don't get the point about how it is revolutionnary, apart from the first introduction of Yoshi.

Let me give you a hint. It wasn't. The game was basicly a improvement in the Gameplay aspect of Super Mario bros 3.
Though the level designs and much diffrent. Its this diffrence that makes Mario World the best 2-D mario game. That's my
opnion don't flame me

Super Mario Galaxy is the much superior game. NSMBWii is innovative enough but for me it didn't have nearly the sense of awe and wonder that Galaxy did.

well I finished both 4 times, and I have almost half time for NSMBWii, but I finshed 4 times not files aka twice with m&l
but the second file in smg i didn't feel like finishing i jut did it for compromise and now I feel like finishing mbwii again so I second my vote by saying nsmbwii again

Super Mario Galaxy, which is in my opinion the definitive Wii game.

I have yet to play NSMBW alone.
And (almost) every game you play with friends is fun.

NSMBWii is more fun, but SMG was enjoyable as well.
