By this I mean some sort of media IP, but one that isn't privately owned. How could an IP like this be managed, including characters, lore, etc?
Sort of related, but Pulgasari is rad as fuck and it would be cool to turn it into some kind of shared project. Maybe a dumb idea, but I just think it would be neat.
I think SCP would be a good example, as it's a crowd-sourced project under CC-SA.
Oh yeah, you're right. I didn't even think about that one.
