I don't think that I'd want more FF characters. They were meant as cameos. More original SE characters, on the other hand, I'd like. To be perfectly honest, in KH there really only was Sora, Kairi, Riku and Ansem. With the addition of the BHK and the Organization, I think that problem has been fixed.

I could also do with some larger worlds, and if I'm not mistaken somewhere along the lines I read something about the worlds being a lot more in-depth. Don't quote me on that, though.

I also remember reading somewhere that some train in Twilight Town or something was going to be the main form of transportation and the Gummi ship was going to be some sort of side-quest thing. Again, I have no idea where I read that and there's a good chance it's just some strange rumour.

Some more original worlds would be nice. Twilight Town, I think, is a step in the right direction. Sure, I love the Disney worlds, but for me, Traverse Town, Destiny Islands, Hollow Bastion and the End of the World were the only real ones. And to be honest, Destiny Islands was such a small part of the game that it didn't matter much and the End of the World didn't have any substance to it. It was just a way to throw in some extra bosses and some relatively difficult battles.

And while I'm discussing worlds, I want more of them. Not just new ones (which we're obviously getting) I want more of them. Maybe it's because the worlds were all so small, but I felt like I just blew through the game. Either they should have as many larger worlds, or more worlds of the same size. Or maybe more larger worlds, that'd be ideal.

As far as everyone complaining about that camera... I never really noticed any sort of problem with it. Guess it's all person preference.
