Nintendo is using the same Mario sprites, engine from New Super Mario Bros. and updating it into 3D. Level design looks awkward.
Gameplay looks slow.
Nintendo! We would have bought New Super Mario Bros.
Add some new power-ups and think of some new environments and the fanbase loves you!
I don't get them.
Reggie's a little confused in the trailer, saying that this is the first "mario platformer created from scratch on a handheld."
Clearly he just forgot about New Super Mario Bros., my favorite Mario game--of all time, I said it! Yes, I think it actually improves on SMB3 and SMW and is a worthy successor. 3DS, of course, is using textures and everything else from NSMB!
Anyway, best of luck to Mario 3DS, I never really enjoyed this kind of 3D platformer, but I'll try it out on a store display hopefully.
Watch the official Trailer on IGN if you want.
