The story has the same "Bowser captures Peach" clichê, but, like Super Mario Galaxy has a pretty interising backstory, not only that stupid "Save Peach from Bowser" and blah blah blah.
The gameplay is pretty much the same of SMG, which is one of my favorite games, with some additions, the game looks like that 2D parts of SMG, the new additions are cool thing.
Meh, that same roster, Mario and Luigi are the only playable characters, the villians are Bowser, Koopalings, Kamek, Virtual Mario (which I think which is a pretty nice concept), Boom Boom and Pom Pom. The supporting characters are okay too.
The worlds names and the level names are pretty cool like NSMBU, every stage has your own name, which is awesome. The level names aren't that fucking same levels like "Mushroom Plains", they are original and awesome.
Meh, I have seen those power-ups before, the only problem here is which none of the power-ups are new and they are very used. Anyway, the description of they are kewl. I also liked the idea of the machines.
A pretty nice concept for a Mario game, totally awesome. But, some concepts are too much used, but, this game deserves 90/100.
