Re:Coded Can't square enix run out of disney worlds to go to?

That's one of the reason's why they use they same worlds over again, so they don't use all of them up. That, and to make the games feel more connected. Also, I really don't think Kingdom Hearts will be another Final Fantasy, it will end eventually.

 

There are a lot of films that they've made, there's new ones all the time. I don't think they could possibly run out since the number there are now compared to how long it takes to produce a new KH game has a significant difference. Sure there are loads of films that wouldn't work in Kingdom hearts but there is still a large diversity to chose from. I think it'll be a while before they run out, plus they're are sequels and the characters can just return to the worlds and a new storyline could be produced.
