This game isn't meant to be immersive nor logical. I mean, you fight bad guys by having sex with them on the battlefield for goodness sake. It takes on an absurdist approach, especially on the masculinity aesthetics. And that's the style Hyao stuck with. Why else would everyone, including their grampas be a bara hunka-loompa in this world. Even the animals are... bara hunka-licious. It's a game meant for suspending ones disbelief.
There's been plenty, and I mean, plenty of debates like these before with straight male gazed games and their obsession with watermelon boobs. And they never really conform with what people deem "realistic" and just do what they want because it's not really meant for the masses.
But alright, let's apply all that anatomically correct logic to all of the game:
- Bernard wouldn't be buff because he's just a merchant. He wouldn't even need all that muscle to do his job and livelihood in such a small town anyway. He would be lean with only a bit of muscularity, but he wouldn't be big.
- The bandits would all be skinny as well since apparently they have a supply problem and they can be beaten by a mere herbalist, further supporting this point that they're probably weaker from their lack of supplies.
- The lizards wouldn't have pecs because realistically, they're not mammals who would need nipples. They would look more like the lizardmen from Divinity Original Sin 2.
- A huge majority of the men in Bareshade wouldn't even be buff because only Logan has a homemade gym and I doubt he would share it with the rest of the people.
- Heck, even the Nameless One wouldn't even need all that muscle because his greatest asset is his mind. A character like that already exist in another game called BG3 and no thank you, I prefer the Nameless One.
So that would be what... a huge chunk of the Lower Aigran side being unappealing (at least to bara lovers), leaving only Logan and Gunnar who both have physically demanding jobs, to be the more appealing romanceable/fuckable candidates. In a Bara porn game.
Might as well just play Skyrim with sex mods or DOS2 lol. because excluding the Argonians, the body types there are much more logical and realistic.
EDIT: I hope you don't take this as me being mean lol. I was reading what I was writing in my head and it doesn't seem dickish in my voice but I don't really know how other people would take and read these. So yeah, just clarifying.
