ut i'd rather a proper, flagship 2d Mario adventure rather than throwaway Mario party fun.
Mario Galaxy 2 isn't far off. NSMB Wii is said to be a full on mario game, not just something they did for MP.
As long as the levels are challenging enough in SP and nothing in the game looks like its made just for MP, I'll be happy. I'll probably play through the game with my sister as she was hooked on the DS version.
