So Nintendo heard that we wanted a game with a story and experience points and Paper Mario in it.
I was hoping for a real Paper Mario game, but I won't say no to a new Mario & Luigi (as long as it's a real Mario & Luigi, which so far all of them have been). If both Bowsers have dialogue and both Peaches do something, this could be really good. Papercraft battles look really neat.
Interesting note: In the Treehouse stream, it was mentioned that the basic setup for the story is that Luigi is clumsy and knocks over a book and all the paper characters come out of it. It'd be nice if he'd knocked over one of the first three books so there'd be more characters than Toads, but so far it looks like it's the Sticker Star book.
