This likely won’t happen, but I can’t get this idea out of my head.
Taking over the TL theatre area, and the games, all before the TL signage is…
Animal Crossing!
It would be the most “tame” IP for a park with the word adventure in it’s title, but since the game is a bit of a choose your own adventure anyways, there could be some fun interactivity that creative can come up with. IOA needs help with the little ones and it would be a nice peaceful transition from MSHI.
