Stealth

The level design is some of the best in the series

I think my favourite is still Super Mario World, but that's entirely subjective with very little objectivity on my part.

Indeed, that's a really nice box art. Also, yeah NSMBU is one of the best 2D Marios. I personally still prefer SMB3, but U isn't no slouch either. Also the newly added characters and content is really nice.

Actually this one of the few Wii U I never bought so maybe I'll pick this up.

Wii is my favorite

Great game, only thing it does not have going for it is big nostalgia.

So weird that Toadette isn't on the box art but her transformation into Peach is lol

Nearly everyone on Nintendo's twitter is booing this lol. Like, when did it become cool to hate Mario U? It's a goooood ooone.

So close to that Super Mario 2 feel.
