Flawed but fun, as others have already said. I really liked the combat system, some others seem to hate it. The localization is a bit iffy, with dialogue and dubbing oddities as dark10x points out...if you get Keith's ultimate weapon, be prepared for one of the fruitiest cutscenes you'll ever see. However, the setting is refreshingly different, and the characters have a lot of charm to them.
As for the plot, it is most enjoyable when working on a smaller scale. The larger story arc is pretty standard JRPG stuff (though with darker themes than most), but there are many moments where the story strays from that formula to focus on a small village, a minor character, etc. That's where the game is at its best.
