I just picked this up about a week ago. I'm someway into the story. So far, it's pretty good....I'm more of an Oblivion fan, though.
Anything is better than that piece of garbage Final Fantasy XII....way for square to drop the ball on that one. I honestly think it's the worst of the series, including FF X-2, which was a 13 y/o's sick fantasy.
Anyways, a good (though somewhat childish and corny, at times) RPG that my girlfriend and I completed for X360 was Eternal Sonata. It's one of the very few multiplayer RPGS, and we had an absolute blast playing it. I really hope they release a sequel.
