I really like what was said here.
It really doesn't matter to me whether or not they're going to be popular, it's just about whether the game is going to benefit from adding them. In past Kingdom Hearts games, we've included a number of more minor titles. It's not only about what's interesting, it's also about variety. Of course, even after that fixed point when we have decided what the worlds are going to be, occassionally there are Disney things that come up afterwards, and I'm like, 'Ah, I wish I could put that in there.'
Wonder how many worlds we would have gotten if they didn't lose that 1 year development.
