How can Kingdom Hearts appeal more to mainstream Disney fans?

I think the game should also be partially developed here in the United States, instead of fully in Japan.

Having two separate development teams working on the same game from two different countries seems like an absolute nightmare to me, to be completely honest.

What would make you say that? We are trying to appeal to mainstream Disney fans, and I mean AMERICAN Disney fans, right? Perhaps the SE American subsidiary, Square Enix, Inc. , should develop the game with American Disney staff...

The Japanese are interested in Japanese fans, and Americans are just an added bonus. Seriously, the first thing they consider is their own country, which is not so hard to imagine. Don't forget that there are a lot of Disney fans in Japan as well (which is one of the main reasons KH even exists).
