Yes, and that's what i mean, there are so many characters in Rayman but only the main character is playable, or it should be an idea to make an online multiplayer function with all Rayman characters to choose.
But it's may nicer that some of the amazing unlockable stuff can be unlocked by getting better times, so that you also have something nice to do when you allready finished the game.
I think a game with ALL baddies would rock... Antitoons, Hunters, Livingstones, Mothes, Stonemen, Flying Pirates, Spiders, Clowns, Robo-Pirates, Hoodlums, Knaarens, etc...
