Not completely original, yet worth buying.
Fighting sometimes feels repetitive, and you will want to continue the story rather than having to step back and fight "random" encounters, though they're sometimes necessary to have the stronger party you may need. There is still plenty of challenge as a result, however, since the enemies you fight are usually a few levels higher and thus a bit stronger.
In the end, I find myself enjoying the game. Wi-Fi isn't too impressive (but the rewards of winning in battle are nice), but sticking to the storyline is the most enjoyable part of the game. Because the sometimes choppy graphics and only mediocre music doesn't come off as a hook to play, the story and methods of combat are the most enjoyable part. It's definitely worth picking up, especially if you're looking for something with a pretty good story, and yet still simple, yet difficult, game to play.
