What would we do in this open world? What could we find? Which secret areas will there be? Will there be any "prize" for finding a secret area? What would make the exploration worthwhile? Are we actually going to do something that can't be done in games like Super Mario Galaxy or Super Mario 64?
There's too much things that would have to be done to have a worthwhile open-world Mario, that doesn't have a empty world, actually give you a incentive for exploring the place, even if it is a beautiful sight, like those places in Xenoblade Chronicles, and you do different things to the usual 3D Mario, then yes it would be great to have one, but if not, I would prefer to stay with what Super Mario Galaxy and Super Mario 64 brings.
