I'm really enjoying it so far. The camera is much better. I haven't lost track of an enemy yet. I love the reaction commands. They really add flash and coolness to battles(especially boss battles). As a matter of fact, the game as a whole has ramped up the flash/coolness factor. Sora's transformations and Sora-plus-current-Disney-character super moves are awesome to behold. Another major plus is that Donald and Goofy are actually useful in battle(in KH1 they were only useful for healing and cannon fodder). There have been numerous times when they've struck the final blow to an enemy. There are only two things that have annoyed me so far(I only just finished the Land of Dragons level). The first is that Setzer doesn't look anything at all like, well...Setzer. The second is Aerith's voice. Poor girl cannot act. Yeah, only minor complaints. I'm really enjoying it so far. With this and Suikoden V(which I will make a thread for when I beat it), I'm gonna be really busy.
Fujin does NOT.TALK.LIKE.THIS.ANYMORE.
Well, it was a major character quirk of hers, so it makes since that they would put it in. Besides, didn't she only talk normal when she spoke with Seifer after you beat him(it's been a while since I played the game so I'm not sure)? I thought she only did that because the moment called for it. I don't really remember the game implying that she stopped talking in one word sentences all together. As for the others, I thought they're personalities were dead on. Of course, we didn't see much of Vivi's true personality...
