Gender of who is murdered has a lot to do with it too. I don't think you'll find a video game where you predominantly kill women. The most infamous scene of murder in video games is the Call of Duty mission "No Russian" where you optionally commit terrorism at an airport. If you pay attention you'll notice they kill much more men than women, and made sure that despite pleasant weather none of the women were wearing dresses or skirts. Murder of men is a lot more digestible.
This genuinely baffles me. Who cares! It's a video game. It's pixels on a screen. True crime podcasts and movies are a-okay but when its a video game that's where the line is drawn?
and never children.
Then you have an open world game where you can do all sorts of insane stuff, but everyone loses their shit specifically over feeding suffragettes to alligators.
GTA, Elder Scrolls and Fallout series all allow for violence against women and not just the mutual violence of combat or whatever. One small example in one game from a long-ass time ago isn't really a broader trend (not to say that society at large doesn't view violence against men and women differently in different contexts)
