There’s a mod for Fallout 4 PC version that makes children in the game killable, in case you want to, you know, kill kids. By default they’re not mortal. Once of the reasons this exists, according to an article on Kotaku is to increase the immersive factor in the game.
That’s a weird hill to plant your flag on.
Consider for a moment that people who want this mod want a game that’s more immersive then consider some of the very gamey game mechanics that would still remain:
My in-game character, who isn’t very strong, can carry 230 pounds and still run. He packs about 10 different guns, which he can access mid-combat almost instantly. Ridiculous. He lives in a world that contains ghouls, which are supposed to be the radioactive remnants of people who’ve been affected by radiation and turned into something that’s effectively a zombie. Ridiculous. There are a number of other game mechanics that break immersiveness, such as healing through stimpacks, ammo that has no weight, and just the amount of junk you can carry around.
So are you really going to base your sense of what’s immersive on whether you can kill children in the game? What the hell is up with that?
