This was definetly a rather good Kingdom hearts game. the story was a bit ok very stumping at first, but it explained its self. I liked how that most of the endings of the worlds were like a mini game instead of a boss battle so that made it fun instead a normal and tedious boss battle. the level up system reminded me too much of the one in 365/2 and was rather boring. Overall I'd give this game a 10 out of 10
I have never finished a non main storyline game but of all of them (I've played at least 5 hours of each) this is the most fun. The story is a little ridiculous and the levels are just getting boring at this point - but this is still a solid game for any hardcore fan.
My PSP just went missing so I haven't played BBS a whole lot and that one looked most promising.
