I think you mean VII Kaylore. XII is twelve and hasnt come out yet.
I liked VIII! I liked the story. The only thing about 8 I didnt like was the weapons. I didnt like having to modify the weapons you start with to get better weapons. Id rather just find or buy a better one ya know. The card game had me hooked for endless hours on 8 though and the airship in 8, The Ragnarok, was by far the best airship in teh series.
