Serious talk: I really wonder why some third party developer couldn't just pick up the movie licensed for Super Mario Galaxy: The Movie and just make a multi-platform game out of it. I have a feeling that Nintendo might have first dibs on a licensed movie game. But I get the impression that they have no interested in making a tie-in game based on any of the new Mario movie's.
What's stopping Sony Computer Entertainment, UBI Soft or some other publisher from just picking up the movie license from the upcoming Mario Movie? release it multi-platform, and based everything directly on the movie cannon. What if Activision picked up the movie license rights? Or Rare under Microsoft? It would technically be base don the movie IP and not the game IP.
