Skies of Arcadia is a AA title according to me, its one of my favorite RPGs of all time, and I can't quite see why, because I personally dislike the fighting system quite a bit.
The overworld map is the best one I've ever seen, for any game, EVER. Its just so HUGE, and it came across perfectly throughout the game, complete with all the little nooks and crannies you can search in for finding more discoveries.
The optional fights are quite difficult if you fight them when theyre first allowed to be fought, which is definately a good thing for me, its very hard to find RPG's that have difficult fights, and this one definately had a few of those.
The characters, though a few are annoying, I actually could relate to them more than most other games I've ever played, even if they were shallow, and the story was VERY cliche, it was a damn good story because of the characters that made it. I'm most likely going to play through this game again very soon, I had 65 hours on it last time, and I want to get Vyse the Legend next time I play through it....
