I feel really hollow knowing that the worlds are based on more recent Disney movies. I like those movies but KH3 feels like it is missing something. I really hope the worlds that weren’t outsourced, the ones that weren’t included in this leak, are the Emperor’s New Groove, Atlantis, and Lilo and Stitch.
These worlds have often been asked for for Kingdom Hearts 3. The aesthetics of Emperor and Atlantis would look absolutely gorgeous in Kingdom Hearts 3, and they have overarching plot relevance too (Atlantis with the heart, Emperor with developing friendships and sacrifice). Lilo and Stitch would close out the story that started in Birth by Sleep and continued in Kingdom Hearts 2.
Discussions have occurred where people fear that the Kingdom Hearts 3 worlds so far are similar in aesthetics... Big Hero 6, Toy Story, and Monsters Inc are modernised US cities. Having the Inca Empire, underwater old fashioned city, and a small beach town with rainforest and the ocean would be refreshing against these US city environments.
