There is blood splatter, but it looks silly, when you loot things off of dead bodies they still have the same suit/helmet/whatever left on their bodies you supposedly just looted.
I’ve put over a hundred hours into the game, I’m not a teenager, and the game is definitely more tame/sterile/corporate in many aspects compared to previous games. Remember bloody mess in Fallout? Or the fact you can goo enemies with laser weapons? Yes fallout under beth is definitely more tame even then compared to Fallout 1 and 2 but still Starfield has none of that.
There’s dibellla in Elder Scrolls, and cannibalism, and skeletons (im mot talking about like necromancer skeletons, literally bones for corpses of prior-dead, in Starfield there are corpses but it’s always the “frozen over” look, even on warm planets with atmosphere where decomposition should definitely have taken place instead)
