I just want to say, I feel the same way! Though, I think it might just be me, but everytime I play an rpg game, I always want to stick with the original name instead of having to come up with one. It feels just right to do so. Like for instance, with Pokemon games, especially the older ones, I would perfer to name him Red than any other.
But, I have never thought about the consequences if you do change/customize your character from the original canon base. I would say that would be a pretty neat feature to add!
So a +1 in my boat lol.
