Hey, perhaps you could give this game a "Steamboat Willie"makeover?. The original Mickey and Minnie Mouse are now public domain and can be used for any purpose, including to make money!. So long as they remain recognizeable as being from that original short, and not any future version. So they can't be in color, and they can't be voiced.

Tons no doubt. It was a long time coming, and would've happened a full 25 years earlier if Disney didn't lobby for a copyright term extension under false pretenses. I think a great thing for game developers is the possibility of using him as a Mario replacement, especially for fan projects that no longer have to be "fan projects" because of this. They can be legally distinct now while still having an appealing and recognisable mascot character.
