I'm not exactly sure what you're going for, but making it like a story mode would be awesome. Like, there could be all sorts of different contests that lead to the Olympics or something. And then make different branches like Racing, Moguls, Slopestyle, Halfpipe, Aerials (Get at me). And then there could be other stuff like sponsorships, meeting pros, movie appearances. Basically, make the game as big as possible with a lot to do.
