I really only had one complaint -- NSMB Wii was only fun with 4 players. The level design was geared 100% to having 4 players which made the game slow and boring in single player mode.
So...
Either go back to a single player gameplay or support online so that when I don't have 3 friends to play with the game can still be fun to play.
Also a "retro" mode would be awesome. aka take the nice shiny new graphics and let you downgrade them to 8 and 16 bit visuals on the fly.
