Okay, so I haven't played it in a few months, and I thought I had 99%. But then today I decided to play it since I've already beaten XII. So I opened up the "Load Game" thingy and I looked at my file and it said 100%. I have no clue how I got it! Every time you save it, it shows you how much percent you have, so I would have known that I had it. And I remember there was one thing that I never did. Something about raising chocobos. I never finished that, yet I still got 100%! I'm not complaining, I just don't know how this happened.
