I kind of agree. I've replayed all of the ones I've beaten (VI through X-2) but I've yet to get the desire to replay XII. It doesn't even sound like a remotely pleasurable experience.

I can't really pinpoint why this is either, since I didn't think it was bad by any means (I actually quite liked it), and it's not like any of the others have anything new on a second playthrough, yet I still want to replay them every so often.

Maybe I just have to give it more time. I had to wait a good five years before IX made me want to replay it.
