How about just a sequel to Super Mario 64? Thats what most people want anyway. Then later, just do a mario sunshine 2 and/or (preferably and) Super Mario Galaxy 3. Just do them all for the Wii U. Who said there has to be 1 mario 3d game per system....that sucks.
And while your at it Nintendo, bring N64 games to WII U an give them all online play. Infact, just bring all the old school stuff back and add online multiplayer. That will boost your sales of the Wii U immediatel...
Its a damn shame when a last generation game is considered the #1 game on a next gen system.........
