What would have sold most? 3D World, Galaxy 3, or a Mario 64 successor?

Hmm, Galaxy 3 I`d go with. 3D World is great, but it has people divided. Some people love it, and some don`t, saying it`s not a true 3D Mario game that is dearly needed. And Mario 64 would likely only appeal to old fans purely on nostalgia. Unless it was a re-imagining, it wouldn`t move much units either. MG3 though people want, and they say MG 1 and 2 are some of the best Mario games to date.
