I was just about to steam in here and point out that Bethesda use sliders just FINE in their games, and what do you know, they gave them a shout out. :P
Well, to be fair, Bethesda NEEDS sliders, because they have always made the fugliest characters around, so they definitely cannot be trusted with presets. Ok, there are A COUPLE of decent-looking NPCs in Fallout 4 and even Skyrim, but appearance mods are always among the first and most popular for their games, haha.
Yarnhead guy doesn't get a say in character design, though, right? Though the Tremere intro video did have a dread-headed white guy... lol
