I've never done a challenge for this game.
I've never solo Magic God Kefka even though I know how.
I've actually been killed by Magic God Kefka before not counting a first playthrough. I learned the hard way that if you toy with him, he does know Ultima...
I've never chosen the Golden Hairpin over Mog
I've gotten a Game Over before for screwing up the Opera too many times.
I purposely kill Cid off and have only saved him once just to see what would happen.
I have never collected all of Gau's Rages, I tried once and have refused to do it ever since.
