Also set up a standardized licensing process that breaks the mini-monopolies of exclusive content.
Personally, I’d also limit copyright to specific works and not the characters, setting, etc. Then protect trademarks and use those to establish canon. Like in the MCU and DC universes, Spiderman and Batman don’t exist together, but in the Superhero Fan Universe, they are roommates and play genius billionaire vs superhuman with a sixth sense prank wars on each other.
When trying to find a copy of Forza 4 (or one of them) after being disappointed with the cut down version they had on gamepass, I discovered it couldn’t be sold anymore because of a deal MS made with Porsche that eventually ran out.
