It’s a game, not a simulation. ;)
It’s a game set in the historical setting.
Ghouls, orcs, magic… the setting in BB is hardly historical! And talking about simulation or lack-there of, there is no penalty for not sleeping every day because it would be boring to wait for your bros to sleep everyday. There is no penalty for not getting a balanced diet. You cannot really survive on only grain everyday, but the game doesn’t care. Managing the diet of your company is not the focus of the game. Do I need to go on? Gameplay is more important than realism.
I think what you are trying to say is something like the possible danger of encountering something you absolutely cannot fight in the early game ADDS to the excitement and how it adds to the flavor of the game experience and makes your victories feel sweeter. Horrible things happening to you through no fault of your own is something you’d expect in a game of the harsh life of a mercenary company. Or something like that. Hrm. I think I can accept that.
