Actually, I referred with my example to the appearance as well as that's what ESO does very nicely.
There's a certain irony that ESO does that but FO4 has removed all support for face randomisation: which I mention as I'm creating a mod with several NPCs and the process of adding them has probably become the most tedious part of the experience!
Er anyway, yeah, I'm all for both extra customisation
and extra convenience when it comes to character design.
