Three words for you: Don't. Buy. It.
Graphic - I for one believe that graphic isn't everything, that gameplay is more important. But a powerhouse like PSP just shouldn't have graphics like this on it. It's no more detailed than, say, FFTA or Riviera. The control sucks, when you walk in town it feels like you are sliding on ice. just plain awful. Gameplay is boring and confusing, and you just dont' have the motive to learn how to play because everything else about this game sucks equally well.
Story/character - LAME! It is unoriginal, uncreative, and it feels like you've heard the same story for about the gazillionth time - demon and humans fought over the world. Then there's a short lived peace but now some villain's gonna start the war again! OH Noooo! The only thing lamer than the story setting is its cast of character. You cannot find a more blend, generic, done to death cast in any modern game, ever. (Gray, Spikey haired hero, young, cute female general... and many more)
Load time - I'll tell you how bad this loading time is. It is everywhere. Conversation between two character: one finishes, load for 5 sec, the other speaks, load, then the first one speaks again. Repeat. It's understandable if it was voiced over, but it's not. It is all text and it takes about 15 loads to finish off a conversation. Unimaginable places like accessing menus takes time to load as well.
