Also, I beat the first campaign of Kingdom Hearts: Birth by Sleep, Terra's, and I'd like to share something I noticed. Remember how everybody complained Kingdom Hearts 2 was too easy? Well, Square listened.
Oh, boy, did they listen.
The difficulty of the game is actually very fair, up to a point. The difficulty spike of Terra's final boss (not going to spoil much here) is ludicrous. He's basically a copy of you, and has all of the abilities you had prior to entering the fight. In this regard, whatever preperations you had for the boss can be used right back at you, including your limit breaks, shotlocks, and healing spells. The ONLY way to do serious damage against him is to block and counter his attacks (which, by the way, if you get caught in one of his combos, you are DONE), deflect his ranged attacks back at him, or abuse your own shotlock and constantly recharge it with Elixers. Now, it's only natural that a final boss would be hard, but this one seemed overly so, especially compared to everything we'd fought prior to him.
Terra's story, at least, was interesting. I'll be starting Ventus' campaign next.
