Under-rated, but not revolutionary.
The graphics are very nice, however the character models are quite simple and a bit childish.
I would say the music fits the game very well, and the voices and sounds are quite effective (although there are a few really annoying characters).
If you persist and can see past the bland story though, you`ll find great game play, an outstanding skill development system and some really fun battles and mini-games.
In order to complete all the side quests, you`ll need to put in quite a few hours, so I would say it`s definitely worth buying if you can find it for $20 or less. I had a very good time playing through it, but it`s not anything that hasn`t been done before.
