This one may seem a little silly, but I figured I'd throw it out there.

Maybe I was OCD, but in Pokemon, I always named the main character Ash... At least in Red, Blue, and Yellow.

I thought we were going to point out things like Terra's name being changed from the Japanese version's name, Tina.

"Maybe I was OCD, but in Pokemon, I always named the main character Ash... At least in Red, Blue, and Yellow."

I changed Edgar's name to Gerad. So later on in the game, the dialogue is screwed because Edgar assumes a new identity, calling himself Gerad. "That Gerad person looks exactly like...Gerad! But how? And Gerad behaves nothing like Gerad..."
 
The devs also did a bit of renaming too: What were once Cafés in the original SNES version have subsequently been renamed to Pubs. Yet when you enter the building, the overlay will still show CAFE. 
And Fenixdowns have been changed to Phoenixdowns.

I changed Locke's name to Brandon. Also Squall's, Cloud's, Bartz's, Zidane's, Cecil's, and Tidus'. This Brandon fellow is like the new Link (except in Oracle of Seasons, that dude was Brandon, too).

When I got older, I kept the original names.

I rename all my RPG characters to the different beams from the Metroid series.

For example for FFVI it would go:

Terra - Wave

Locke - Charge

Edgar - Ice

Sabin - Plaz

etc.

I would eventually run out of beams and would have to get a little bit more creative from there, but I always go through the beams before anything else...dont really know why.

Here's my name change Final Fantasy VI - Shit.

I kid, I kid. I changed none of them.
