Yes it's got some new graphics, music and power ups, but do you think things like the bosses, items and general theme will be more original than in New Super Mario Bros 2?
I think it'll be a lot more original than NSMB2. Although NSMB2 has some great level design, there aren't really any new ideas in it at all. But to be honest, I think the bosses in NSMBU are going to be the Koopalings again anyways. Still, the new music, power-up, Yoshis, and fifth player options make the overall experience much more original.
