The game is actually fun now. They changed your base combat so that the combos actually work instead of enemies falling out of magic flash for the 2 billionth time; they expanded the best world in the game and gave you a lot to explore; they added in oathkeeper and oblivon, which have the best formchanges; all of the new bosses (armored xehanort, yozora, data organization) are fantastic, I hate the wall around the arenas, but aside from that these are the best bosses in the series.

KH2 was lightning in a bottle, and for a brief moment, that lightning came back and made this DLC rival the best of KH2. I've never been more excited for the future of the series, and I hope that KH4 is a good game as a whole, and doesn't just have a good final mix expansion.
