Well most complaints I've heard boil down to either the story, which, like, if you don't like the story complexity you probably checked out after Chain of Memories and need to leave the people still invested in it alone, or that there aren't enough new innovations to the gameplay, that it's too much like KH2, or something, but I liked that game, so I don't see how that's a problem. I also heard something about the camera not following your character closely enough, but that was from a nitpicky friend of mine and overall nothing has made me doubt that I'll enjoy the game when I finally get my hands on it. That's disappointing to hear about the Disney worlds and the length, but so long as I can squeeze 40 hours out of it I won't be upset, and I'm a completionist so no worries there. Glad to hear Tangled was good. Of the worlds I've heard about so far, that was one of the ones I was really looking forward to. The short one isn't Toy Story is it? Please say no...
Thanks for the spoiler free review though, and yeah, with Yoko Shimomura at the helm, Kingdom Hearts always has some of the best music.
Yeah, I haven't had any problems with the gameplay or story so far. I especially don't see how people can complain about the combat, it is by far the most complex combat system in the series with tons of different options; standard keyblade melee, shotlock, flowmotion attacks, attractions, links, magic, keyblade transformations, and partner co-op attacks.
The Toy Story would was shorter than I was hoping for, but it's not the short one I was referring to, the short one is Winnie the Pooh, it's like 20-25 minutes long.
