Does this one really need explaining? It's a bunch of worlds from various Disney animated features tied together. You could call this Disney's version of The Avengers, were it not for the fact that The Avengers is actually already Disney's version of The Avengers. One can only guess as to why this isn't already a thing being some sort of hang-up on Square Enix's end, though with their recent financial reports, one would think they'd be more receptive to an easy source of money from one of their most prominent business partners. So who can say?
