Birdo's game could consist of creating movie parodies, where Birdo is the star of several movies, with Mario characters filling in the cast. That wouldn't be a bad idea. I don't know how it would play, but that would be a good storyline for Birdo. I think I came up with an idea like this before...
As far as Mario platformers go, though, words get in the way. I want to jump, run, and throw fireballs, with all message and info boxes being available, but unnecessary.
