I played the Blue Dragon demo too and the game wasn't really what I was expecting. Graphics looked nice and all, but the game seems aimed at 12 year olds. The tower part was way better than the forest, but the dialog and all was really childish. Probably doesn't help that all the characters look and sound like they haven't hit puberty yet either.
I'm sure it'll be fun because I didn't mind the gameplay too much, but the story didn't seem very exciting from the demo.
