A good addition to the series with some unique features but presented in a difficult fashion.
The Good:
As with any KH game the score in this game is awesome.
The gameplay in this title features a unique leveling mechanic and melding feature for spells and moves. I personally found this feature very addicting and I would sometimes just work on leveling or making new moves rather than follow the story. Other than the new feature combat is pretty similar to other KH games, not including the card system from CofM.
Other than that the game featured solid Disney, Square, and KH content with an enjoyable plot. I also enjoyed the addition of the Command Board mini game. It reminded me slightly of Mario Party and it also allowed me to further level my skills while unlocking more skills.
The Bad:
The camera annoys me but then again that is true for pretty much any KH game.
You have to complete the story with all 3 characters before unlocking the final sequence. This isn't necessarily a problem but considering it takes probably almost 10 hours to complete each character's story only following the plot and they visit all the same worlds it can get somewhat repetitive or boring. Granted the character are doing their own thing at each world, it can still seem kinda repetitive or at least I thought so.
Overall this is a good game and addition the the KH series. Its repetitive nature with the three plots may weed out some players who aren't really into the KH series but for those who can get past that and the die hard KH players its a great game. Aqua is my favorite ;) other than Roxas.
