Kingdom Hearts 4 director Tetsuya Nomura has addressed concerns about the lack of Final Fantasy characters in recent Kingdom Hearts games, explaining that as the series grew over the years, it became less necessary to feature cameos from the long-running RPG series.

Speaking to Game Informer, Nomura added that the “basic concept” of Kingdom Hearts wasn’t a crossover between Disney and Final Fantasy, but rather the story that was told through original characters.
