This game isn't bad but it is extremely lazy. It is just a SNES emulator playing Super Mario All-Stars and not even the version with Super Mario World apart of it. The menus aren't even edited to show Wii controls, it still shows SNES controls. The entire package just screams lazy.
Honestly speaking though, I am not really fussed by this game all too much. I just find it fascinating that Nintendo would release a physical game disc with the only thing on it being one SNES ROM. This thing is just a fun little oddity to own. If you want to play Super Mario All-Stars then this does the job. There are better and more convenient ways of playing Super Mario All-Stars, so I don't see why anyone would ever use this as more than just a decoration on the shelf.
