How to fix Son of a Dungeon looking "video gamey"
Nvidia's got a whole SDK for character rendering that includes skin and hair neural rendering and it might be the thing that helps get the face renders out of the uncanny valley https://github.com/NVIDIA-RTX/RTXCR
It can do subsurface scattering and more realistic diffusion for enhanced reflectivity and more realistic rendering of the materials.
Left a comment on the video about RTX Skin, which is built into the SDK
Edit: Just to clear things up, I don't think the footage they showed looks bad. It looks like a game because it's being rendered in Unreal, which makes a TON of sacrifices to rendering accuracy to run in real time. It's a game engine, not blender. I'm just suggesting Nvidia's SDK because it could help refine the look further without being a massive time sink.
If it were me, I'd just lean even more into the video game aesthetic. Stylize things even more. Would only make the show look more unique and cohesive than it already does.
I think a lot of people are getting hung up on the end result without realizing how flexible this workflow lets them be. It's not JUST about saving time on setups or rendering. They can do any dynamic camera movement and lighting conditions they want. Just because the output doesn't look photorealistic today doesn't mean adopting this sort of workflow early is a waste of time or some sort of creative compromise.
