I don't know about anyone else, but I have a PS3 and I've played the demo through with both characters....the music is awesome.....sometimes I just leave my PS3 on, set to the "folklore demo" graphic and listen to the music it plays. And playing as Ellen was cool, in the sense that one of her physical attacks is to wave her hand, and when she does, a giant, horned, scaly lion fish erupts out of the ground next to her in a shower of flower petals and bands of energy and smashes into whoever's in front of her. Seriously, her moves are sweet. And frankly she's pretty hot, her outfit is cool. Keats is where it's at, though...he looks like Otacon's evil twin, and some weird dude in a black trenchcoat that says stuff in a rough Irish accent is sweet. Also, Ellen just kind of coaxes enemy's souls out when she beats them.....Keats bashes them against the ground until he rips them out. I actually really like this game, and I didn't think I would....I like the battle system WAY more than FFXII, because you hardly go three steps without getting a new ability, or getting enough experience to upgrade the one you already have. I had like 9 for each character by the end of the demo....
EDIT--also, just so everyone knows, every enemy you kill is a potential move, when you kill him you rip out his soul and turn it into a move you assign to one of the face buttons. You can then string the physical ones into combos, and the more you evolve, for example, a multi hit combo move, the more hits the combo allows and the more powerrful it gets. There are moves that launch rockets, or use a flamethrower, or create a giant evil hedgehog that you can make kick everyones asses. At least one of them made an impenetrable shield, and another gave me a machine gun.
