All I have to say is that, unlike Disney sequels, this game surpasses the original in almost every single way. The story is extremely captivating and the worlds and locations of various Disney worlds are great. In terms of gameplay, you just can't seem to stop. You are given brand new ways to fight enemies, including merging with other characters (such as Mulan, Jack Sparrow and Auron)and activating drives, which allowes Sora to weild two keyblades and attack enemies in different ways. Reaction commands also allow new ways to attack enemies. Unlike the first game, which left you wandering around the worlds without any clue of what you were supposed to be doing, KHII gives you a fully interactive atmosphere with plenty of people to talk to. The boss fights, while mostly easy (although they do get extremely hard near the end), are actually FUN to play and are not as frustrating as the ones in the first game (Hydra and Axel are good examples). The whole atmosphere is very enjoyable.
The game also allowes you to visit various worlds from Disney and fight along with some characters from their movies, such as Aladdin, Mulan, Beauty and the Beast, Tron and Pirates of the Carribean.
Ignore the whole Disney theme, even if you enjoy more mature games, you'll be sure to have a blast playing this. Excpect to put around 30 hours into it. 9.8/10
