NSMBW offers a much harder challenge then NSMB. The Wii version has three more items,(propeller mushroom, ice flower, pegin suit) and 9 worlds(one is hidden). The conntrols are easy to use, and it has a mutiplayer mode, for up to 4 PLAYERS! The downside is that it no longer has minigames. I suggest that you out and buy this great game, it delivers a whole new challenge than NSMB for the DS/DSi.
