I wouldn't mind seeing some totally off-the-wall adventure game. Mario can be a bit trippy at times, but just something completely wierd would be fun. Sure, we have some games like Ratchet & Clank out, which are odd, but who needs to play by any sort of scientific rules? It would be neat if he made up his own world, entirely, and populated it entirely. I remember reading some books (xanth series) where they went to these oddly shaped worlds, and each had a theme, they also had a different shape. Because of this shape, gravity acted in a very odd way. Something like this could be fun, really challange gamers.
