I don't even think publishers own the copyrights to the games in all cases. The studios do in many cases. How the heck would that be handled? Leave it to the publisher to get the money to the "rightful owner"? Or does it even matter? And would they even have the financial infrastructure in place to accept the 10%? Not that they'd refuse free money but it could be like trying to pay your $75 speeding ticket to the cop when he hands you the ticket or trying to pay a bill 10 years in advance...you'll be met with "sorry sir, you can't do that" or "we can't enter that into our system". I just don't see this working on so many levels. It actually sounds more like a case of "there's no such thing as bad publicity".
