I used to rename the lead character on my first playthroughs, but now I don't... When I started III on a nes emulator a few months ago I actually tried to find some default names for them, but google let me down and I just named them either randomly after some other characters in a fanfic I wrote or named them with some completely invented names (I even named one what I thought would be a girls name, not realising they're all brothers . This one later became my white mage.)
