I decided to use Unreal Engine to make Kingdom Hearts: Rebirth by Sleep. It is set between KH3 and KH4 in the Vault of Dreams where the half-human half-Heartless main villainess Rogue collects what she considers "Stolen Worlds", worlds that are acquired through theft every time her gold-and-silver coin lands gold side up. These are the worlds:
- World Ghibli (Disney-dubbed Studio Ghibli films): This world (tutorial) is divided into three areas: Howl's Moving Castle-themed Wizard Workshop, Spirit Alley (based on Spirited Away) and the Kiki's Delivery Service-inspired Witches Cape.
- Game Central Station (Wreck-It Ralph
- Château Maudit (Beauty and the Beast
- Olympus (Hercules
- Tomorrowland (Disneyland): This world is based on a themed area at Disneyland
- Arabian Coast (Tokyo DisneySea): The Japanese Disney Park's "port of call" receives the Kingdom Hearts treatment.
- Halloween Bastion: This world was once Radiant Garden until Jack Skellington took over, reducing the world to a Halloween version of itself.
- Kingdom of Corona (Tangled) Another KH3 world returns in Rebirth by Sleep.
