You are right; I was being loose with my language on assets and receipts. Thank you for the correction. > but if that content looks anything like the original asset, they're liable to get sued for copyright infringement. I am thinking something more along the lines of a game that supports in-game mods for it. There is nothing limiting you to use the original asset; you just need proof of ownership to give access to a different functionality. I have no idea how this would work across developers and with copyright, but there are real scenarios right now that would love to use proof of ownership or for mods.
