If you look in my sig, Mystic Quest isn't in my victory list. That's not because I didn't beat it. I did. It just doesn't count because it's classified as a beginner's game. But, yeah. It's a spinoff. So, that's another reason for it not to count. Though, I listed Final Fantasy X-2 in my victory list, so figure that one out.

My vote goes for Final Fantasy X-2. It was the most like the mainstream games and the mainstream games are what I most like.
