This makes me think about a non-Final Fantasy funny thing that happened to me a pair of years ago.
I had started to play Breath of Fire, it was my first RPG ever and I didn't have any idea of how to go through it. So when the game prompted me to enter a name, I thought it was a name to distinguish saved games one from another and I typed "Fra1". That turned out to be the hero's name!!
Until much later in the game, when I got to the underwater village where you could change party people's names, I kept on reading things like "It was all because of Fra1 if Nina was saved!"
