Cheers for the underdog!
With that said, here's the quick and dirty on why this game rocks. The story is amazing! There's intrigue, betrayal, political twists, and touchy subjects like racism all handled in a gripping way. The combat system has some very cool elements similar to the Lunar series, but with emphasis on teams. The ever cool character collection is still as challenging and fun as ever. The base building element rocks. Really just all in all this is a great game with great story. The graphics may feel a little dated, but they're good enough and stylish enough where you won't be bothered by them.
There isn't much bad I can say about this game and more good than i care to write at the moment. If you're still totin a PS2 and can find it, pick it up!
