I've done 10 twice.

The first time took me 105 hours as I strolled through, and the second time only about 60, which I was kind of upset with. That's basically 40 less hours of blitzball playing, which I hadn't realized took up so much time in the game. I've never beaten a FF title in 60 hours. Even when I first started and was racing through 7 & 8, it still took me 75 or so.


Let's I've done

6 - twice
12 - once
