Not a chance. Nintendo would never allow that the happen, not as long as they can slap a Mario skin on something and have consumers eat it up. It doesn't even matter what the game is, at this point. Many of the people who buy a new Mario title have already decided that they will enjoy it before they've played it. How many units would that Mario sticker game have sold if it featured a different, non-Nintendo character? How many people would have been more critical of it? Nintendo knows what they have.
Why everyone (including Nintendo now) ignores the power of the pack-in game, I have no idea.
