Kingdom Hearts 4: 15 Disney Worlds We Need To See
4. Inside Out
Inside Out was a return to form for Pixar after the mediocre Cars 2 and Brave along with the divisive Monsters University.
It has a lot of heart, fun characters, a great message about feelings, and a great world that is just dying to be visited in a future Kingdom Hearts game.
Exploring Riley's Mind as the Sora, Donald, Goofy, Joy, and Sadness would be a lot of fun due to the variety of surrealist and interesting areas found there.
The Emotion Headquarters could be somewhat of a hub in the world.
Long Term Memories is a colourful locale that would be interesting to explore.
Imagination Land and Dream Productions would be an excuse for the Kingdom Hearts team to stretch their creative muscles and think of some awesome ideas to exist alongside what was already established in Inside Out.
Abstract Thought is a must, the Train of Thought could be used to quick travel between locations, and a fight against Jangles the Clown in the Subconscious would be an interestingly creepy encounter.
Use the world as a way to teach Sora something about his own emotions to connect it to Sora's growth as a character and Riley's Mind could be a fan favourite world.
