I bought Kingdom Hearts HD, and after much raging, and 22 hours of gameplay, I FINALLY BEAT THIS GAME. It only took me like 12 years. Childhood=won.
In all reality though, this game hasn't aged all that well, mainly the combat. It is however much more rewarding than Kingdom Hearts 2, since that one I remember being piss easy. I have so many fond memories of copying my brothers save religiously to get to the end, and still not beating it. Well gosh darned it I have won. Now when does 2.5 HD come out?
