i dont really get you,do you mean like NSMB?

^ yeah, 2d game play but 3d graphics...

Check the 1-2 minutes of trial of it in Brawl, I thought that it was funny. I would want it to see how would they make it.

They can make it Nintendo's main buddy-style (Banjo Kazooie) type platforming game. They can focus on various terrain (valleys, forest, rivers) etc. not just mountains.

As for the graphics, it should be full 3D, not 2.5D, since 3D provides much more freedom of movement.

not me sounds like a bad idea my opinion.

yup...I would be interested..played it on brawl masterpieces...looks like an updated version would rock..

WiiWare maybe?

no thanks.
However bring Pilot Wings back.

i think it should stay 2d, when some old games turn 3d they lose something in the process, but i am sure nintendo can do it since they've done it with mario zelda etc

^Well, the only thing you'll lose would be the ability to see what's on the platforms above you, but they've managed to remove that element from Mario in the jump to 3D.

 yeah that would be good
