And explain why if you want.
+ Better Graphics
+ More traditional KH gameplay (Somewhere in between KH1 and KH2)
+ More important to the story then KH: Days (Its not a spin-off unlike Days)
+ Better Main Characters (Terra and Aqua have amazing designs, Roxax wannbe looks average though.)
+ Most likely will have direct links to KH3 in someway.
Still the Lack of Sephiroth is most harassing. since the art-style looks alot like KH2.
