I'd love to see another Super Mario 64, it's one of my favorite Mario games. How about a game that takes the best from Super Mario World on the SNES and the best from Super Mario 64 on the N64 (I just want a rideable Yoshi in it, is that too much to ask? lol)
I love this idea. I loved Sunshine and Galaxy but going back to what started the 3d mario games would give a fresh feeling. Nothing but the pure challenge of platforming. That was one of the best games ever. I really hope they one day consider bringing something like this back, with or without the castle and paintings.
It would make even more sense if they made Mario a 65 year old who can't quite jump the way he used to, get ready to fall into every hole, miss every block, and pretty much be useless!
