I thought I heard there would be an Animal Crossing cartoon.
Animal Crossing fits better in episodic narratives. I'm pretty sure you wouldn't see a movie based on a game about nothing in particular...nothing really epic could happen.
But a cartoon, with a few main characters (maybe a boy, a girl, Tom Nook, the Abel sisters, Pelly, Phyllis, Booker, Copper...you know, the townsfolk in EVERY game...not to mention visitors, and any from the whole slew of 200+ animal neighbours) and silly little narratives about holidays, fishing/bug-catching tournaments, etc...
It might work fairly decently, actually. And probably sell more of any iteration of Animal Crossing.
