Im not a big fan of RPGs, Disney or Squaresoft, but this game is just great. Unlike Final Fantasy games, this one takes a more action-type approach to battle which is why its much more fun in my opinion. Expect the usual stuff from Square like an engaging story tieing the Square universe with the Disney one. My only complaint with this game is it seems too kiddie, bad guys don't necessarily look evil, especially the Heartless.
This game is a turning point in RPGs. Hopefully it will inspire more like this, and not keep to the Final Fantasy roots. There can be great things for this series if they just put a little more of a darker side to the theme. Regardless what I think, Kingdom Hearts is the most fun I've ever had playing a Disney/Final Fantasy inspired game. Check this one out for sure
