I always make myself in a rpg game otherwise i can't enjoy it
It's pretty hard for me to do so.
I'm half Mexican, so that's how I look for the most part (although I can pass off as some kind of Arab-speaking person if I grow out a beard, but not Redguard). Not really a Mexican-looking race. It's to be expected, the games are modeled closely to Europe.
For the human races:
Bretons: Celtic, English, and French people (anybody from Brittany in France?)
Nord: Germanic peoples (specifically Scandinavian)
Imperial: Italian people
Nothing that looks like me XD. It's fine though, I'd much rather play as an elf.
