I think if a regen comes from a certain country e.g. Portugal he will most likely have portugese name. However if a regen comes from a country such as Ghana he will have either a Ghanaian full name or a british first name. Baisically it is the countries background that dertimines the regens names. I think.
I believe you can. I remember reading about someone doing it for fm09.
I don't know if you have to do it from the editor, or some other way.
