i'd say video game violence is a lot less shocking to me personally, i mean because we're used to taking damage and damaging others as the player in a video game, versus watching our favorite protagonists in an epic movie get gruesomely wounded. in one situation we're in control and there's things we can do to change the situation, but when you watch a movie, you have no control or way to help the characters in the movie, so you feel helpless when they're severely hurt through violent acts. because of that i'd say movie violence is far worse, plus considering movies are specifically and specially edited to draw out emotion from the audience as much as possible, via tense music building up, insertion of sounds, and use of specific camera angles to make the violent moments much more intense. this of course can apply to video game cutscenes, but that's still to a lesser degree.
i mean let's be real, there's a ton of violence in video games and we see by volume much more of it, but because of the atmosphere of most games it's not as impactful. we all know that there's a big difference between sniping then t-bagging someone in halo or huntsman tauntkilling in tf2, vs a graphic torture scene in a theatrical film. one side is downright funny and entertaining and the other is 100% serious and emotionally impacting.
