They aren't using facegen anymore, so who knows.
This.
Yep, in Oblivion you could with a lot of work and experience build a face that you liked.
However the difference in face gen and in game world tended to go wild fairly easy in both Oblivion and the FO series.
If they make a good photo fit style generator, we may get lucky.
However it depends on how many options are available.
Thinking about it if you count all the Men races as one oddly, and oddly again make the Mer similar or one bag of features.
You still have argonians, khajiit and orcs.
I hate to say it, but we may not get everything we want in a vanilla game.
As the effort to go into this is astonishing, and frankly up there in the realms of we needed to focus more on other things.
