No, because of the way copyright works, it does have to be that way. No game developer want their copyrighted IP associated with whatever trash game some dipshit edgelord wants to write. Yeah, sure, you can put Mickey Mouse in your loli-rape game. LOL, never going to happen, and you are dumb for thinking it's a good thing.
NO game company is going to let some other IP into their games. And very few games would benefit even from letting in the companies own IP, from other series. As a gamer, I do not want to see your cowboy in my sci fi game.
So, you'd have to give the companies control over what goes into their games. Making the whole concept pointless.
So not only are you wrong, you're an asshole about it to boot, because you haven't thought this through and don't have any actual, good, reasoned arguments in favor. You just want what you want. And critical thinking is obviously not something you want to do.
