I was how good KH2 is? I have heard it's awsome and it sucks. I finally gave the first game a chance and i loved it. Is #2 worth playing as well?
The best part of KH2 is the insane things you can do in battle: Drive Forms, Reaction Commands, Limit Attacks, the various combinations of Abilities. By the end of the game, you're a pure being of stylish destruction.
It's biggest fault is that, because it's so story-focused, you'll find yourself watching more FMVs than fighting. One of my friends described it perfectly by saying that in the first game, you fought and were rewarded with a movie. In KH2, you watch an FMV and are rewarded with a battle.
