I would love if for once, there would be an RPG-esque pokemon. What I mean by this is that there would be a deep and involving storyline. The entire game would be fully 3D, and you would travel around in 3D as well, sorta like Final Fantasy. Battles would happen right there on the screen, without a need to skip to a battle scene. And then you can play as the pokemon with their moves and whatever, turning it into a fighting game of some sort.
That would be my idea that I'd like to see made.
