I'm half way through my second playthrough of XII. :P Life got crazy and I literally didn't have the chance to continue playing it. I'm definitely going to play it when I get my PS2 back in a couple of weeks. :P

I've only finished IX once for some reason. I really loved it, but I just never got around to trying it again. It's on my list.

I finished VII once because it's just not worth a second playthrough.
