Something that frustrates me about most historical fiction is that the hero is almost always out of place and time. The hero and his companions act and hold beliefs like a modern westerner, even when everyone around them doesn't. Even when the belief was so ubiquitous that it was held by 99% of the population. Somehow, your hero is always in that 1%.
This is even worse in RPGs because they offer you a choice, but that choice is usually limited to "be nice like a westerner" or "ignore it."

EXACTLY:
I think you posted this already, but I just wanted to point out the significance of this change.

They changed the model of Henry from KCD 1 to 2 to make him chadified... But: He's not supposed to look like that. If you're playing a witcher, obviously your body will be a mountain of muscules. But you will NOT look like that on a medieval diet. It's just not happening.

@LukeAlmighty I dunno. Here it could simply be a difference in camera angle and ingame vs prerendered. I barely looked at his face in game though since it's covered by a helmet.
He also was acknowledged as a son of a noble so he did probably get access to more meat.
You are correct though that on a medieval peasant's diet you would not be able to build muscle.

@LukeAlmighty also Gerald isn't the best example, because they made him more attractive and human in the games.

@matrix @LukeAlmighty Geralt is one of the worst examples, he's supposed to be lithe and generally off-putting
