If Miiverse is any indication, lots of people out there that are really creative. One aspect I really like about Minecraft in particular is the user generated content.
And the gamepad would be useful in sorting those pieces.
I think it would be a really good darn idea and would keep people enjoying it for a long time. When you release 1 3D Mario per gen usually anyways, I mean why not? Nintendo has too many software droughts already why not rather make the games last for a longer period of time through the users themselves?
Super Mario Unlimited and whatnot.
