Pay a fee and you have the right to distribute the [modified] games. And they can't say no.

It will break some models that rely on sales areas, but instead of take-down notices when someone violates copyright, you simply send a bill, with reasonable, non-punitive rates.

It needs some details to be worked out - in particular the rates, plus how to determine how many times the work was distributed. But those are solvable, and I think it would transform piracy from a problem, to a revenue source.

It would also help avoid all those messy areas where copyright rules cause real problems for people who just want to do something.
