The RPGs Created by bethesda haven't enjoyed great characters. Sure sometimes they shell out for a big voice actor... but they've never gotten the entirity of the characters done right. Be it that their animations are awful, Their malnourished outcasts, decrepit old and gluttonous lords all sharing the same god-like bodies that everyone has. AI is notoriously awful. I'm just wondering; How can they make good characters, outside of paying a big-name to voice a character that we'll likely see once.

I'm confused if you're asking about characters or NPC model diversity.
