As a kid I loved naming my characters silly names or after friends, best friends, family, pets and guys I liked. However as I got older I now hate changing character names from what they were originally. Although when I was younger I use to name Barret from FF7 Barbie and I'd always make the main male character named after my crush at the time and the main female character or the female character that I liked best after my self.. like FF8 I'd always name Rinoa after me. Now I HATE changing the names D': I don't know why but it bothers me to do so! even in other games like Pokemon and Zelda haha.. sweatdrop
I always refused to change a characters name.
I did name characters in the first game after my friends though.
I named my melee character after myself.
My white mage after whoever I had a crush on.
My thief after my best friend.
And my black mage after another friend.
I'm never too partial to renaming characters who already have canon names. I would even get annoyed when a friend would borrow my old Zelda N64 cartridges and make a new game file and not name themselves Link xD
For FF games I'm the same way, though I never personally played the older ones where you could. I watched a friend play through most of VIII and they renamed everyone they could and it just ticked me off, and I don't really even care much about the game. I'm too picky :B
