I always thought the world of Avatar (the last airbender) had a lot of gaming potential. You could make a really cool open world game, with a lot of fun physics.
South Park was onto something
This.
You have all these really popular IP's with fun worlds, lore and characters like Naruto, One Piece, Demonslayer, etc, but all we get are shitty copy pasted arena fighters and Musou games, as well as the occasional low budget cashgrab "adventure" game like world seeker.
If someone would bother to actually get a good studio to make a good single player game with one of these IP's I think it would do extremely well.
The closest we got were those Ubisoft Naruto games, too bad they still felt rather limited and their combat sucked.
DBZ Kakarot is basically another shitty arena fighter. They just added some big empty areas, had you fight the same 3 types of regular enemies from time to time and called it an "rpg".
