Absolutely the best KH game. People always say that this is the best one, and they're right. While losing some of the best parts of KH1, like the integration of the overarching story in with the Disney worlds, or just a lot of the charm of that game, KH2 builds in the other departments. The combat has been significantly enhanced. It's pretty much an entirely new combat system, like how magic got a complete rework from KH1, or how the ground combat got completely undercooked and now aerial combat is the way to go. And then the addition of Drive Forms really change the game. Drive Forms make using normal Sora feel worthless, as Valor (the first form you even get) just sweeps everything. But where the game really shines, other than combat of course, is it's development of the story. It builds up from KH1 and Chain of Memories, and if you're playing in release order (which is how you should), then the brand new characters just show up and have no real introduction, and it brings in this aspect of mystery around them. It is a very great game, and I hope to platinum it soon.
