I don't know I'm afraid, I do know it's out for the PS3 and the 360. It's a newer game.
I'd classify it as a semi-linear RPG. It has a set story line, but you can run around and do any side stuff in any order, meaning you CAN take on more than you can chew and got pwnd. You get to create two characters, (like voice, facial features, hair color, eyes, gender, pretty much anything you can think of) so that is cool.
