Unlike minecraft, even after Microsoft turns it into a business rather than a humble video game, as long as it's Java, I know how to shape it. I know how to make changes to it to fit my preferences, despite it might violate the eula or something, the point it, we as a fan community, we can achieve it in a technical way.

But tv shows/animes are different. Normally, people don't causely purchased the whole IP and redo it. Or even more ridiculous, buy the studio and redo it. That's technically impossible for now. Maybe someday the AI is powerful enough to do so? But considering everyone is eagerly trying to be god, I don't believe the AI will be useful.
