Mario and Donkey Kong in USF as has been talked about here, Zelda in the third park, and Pokemon either also in the third park or IoA. That's what I would do. Speaking of Pokemon an attraction idea has been in my head for a while that would get me very excited even though I don't play it anymore. Imagine an attraction that takes mushion projection and guest participation to a whole new level. An attraction that would bring in fans from all over the world to hopefully take part in it. Two simple words: Pokemon Stadium.
