For like... console boxes that we can't scan? or like collectors edition 3pak sleeves? Most normal people cannot print on said cardboard and would instead be a sellers/resellers market, which sucks when you devote all your time into something for free that others just turn around and sell for $10 each.
Just curious what you are thinking of, as all I am thinking of is people not able to print and others making massive amounts of money off of our communities hard work (without giving the original artists credit / money)
