hrm... there's actually quite a bit of suggested rape in games if you know where to look or how to register the psudo-symbolism... Mind!Rape, Soul!Rape, Physical!Rape, etc. etc. if it involves some kind of non-human/human interactions, especially anything to deal with demons you can bet your ass there's something in there that at the very LEAST suggests rape... maybe my brain is just completely wired for spotting this stuff and i'm jumping to conclusions... but really, its there if you know where to look .-.
its typically coupled with some kind of specifically 'evil' violence, shame, or even abortion overtones, bonus points to demon babies of some kind... Demon's Souls i'm looking at you -.-
random violence/killing in video games is... silly, mostly, to be honest, why don't we take it as serious? because killing is EASY, its as quick and effortless as pushing someone off a bridge of sticking a knife in them... i know there's supposed to be a 'moral issue' when it comes to killing, but we as animals are just as programmed to do it to survive as any other creature, its already there in us to do it... and again, its easy, its just our build up 'society' makes issue with it and tell us its wrong, plus i think on some level no matter how into the game we are, we all know 'its not real', as in that NPC is nothing but someone attacking our character, they have no background, no history, no personality, nothing to them, they are a complete blank meant solely for the purpose of us killing them to get from point A to point B, so you can't even really call it 'murder', but that's getting into a completely other set of morality...
Rape is... well there's a reason there's an entire trope called 'Rape is a special kind of evil', removing the good/evil from it, even still its an act that requires a lot of planning, build up, power, force, etc. etc. and i doubt it simply damages the victim but the attacker as well, but they're usually already damaged anyway... rape actually has very little to do with just 'sex' and more to do with power exertion and humiliation, that requires a much deeper connection then 'killing' does... effectively why does it 'effect' us more? because it requires more effort to comprehend, and we ourselves are more adverse and shamed of it, especially if it happened to us... death is final, trauma is a lifetime thing...
even if we're not playing 'heroes' it takes that extra step in effort to actually go about 'raping our enemies' then just say killing them...
i have no issue with rape being 'in' video games, like i said, if you know where and 'how' to look its already there, just like in comics and movies its hidden under subtlety... and from what i've heard of the 'rape scene' in new Tomb Raider, didn't if you fail that the guy just killed her? so while he's being all creepy, yes, but its not REALLY rape... though it would make sense in the context... its just another one of those 'assumed' scenes, and i have no real issue with this kind of thing... like someone said earlier i think i had more of a reaction from playing Leliana's back story in DA:O... in fact there's A LOT of implied-if-not-openly-stated-rape in Dragon Age: Origins... hmm...
i think its a good thing people get a squicky reaction, it basically means you're less likely to do it, which is good... but yea, no reason to not have it in there... fuck half my issue with visual media is "if they can do it in books why not -insert media here-?" because seriously, books is free reign... suppose the audio/visuals are just an added push on the trauma scale or something *shrugs* psychologically is more disturbing then just imagining it in your own head i suppose...
