If you have never played a Kingdom Hearts game my friend, here is agood place to start.
Story: 8/10
For a story that uses disney characters i'm surprised im not up to my *ss in songs sung by woodland creatures. But then again i wouldn't expect anything less from Tetsuya Nomura. The story is pretty intriguing and well put together.
Gameplay: 10/10
It combines leveling up(what RPG gamers know and love) with free roaming battles. There are a variety of cool skills to learn and use so it always keeps the fights fun. Plus it's not complicated to know how to fight.
Music: 8/10
Pretty damn good. Nothing mind blowing to say here. But the music is good.
Overall: 9/10
Overall it's a pretty good game. Lots of unlockables and secret bosses(you just gotta have secret bosses! That or alternate costumes). I suggest owning it because it's something you want to collect or rent it if you believe you can finish it in a short period of time and never touch it again.
