Sure, I can see that. I totally understand that some adults can handle that stuff and others can't and that this is the case with a lot of things in life.This is a cop out. Adult people should know not to be racist, sexist, addicted to drugs, steal, kill etc but they go ahead and do it anyway. Violence in video games is so rarely targeted like the sexualisation of women is. You're killing zombies, or bandits, or monsters, or demons. If a game had you only killing women with extreme violence, this would be an entirely different conversation. Violence in games is equal opportunity, sexualisation is not.
The thing is that a lot of people can play those games and still behave like good human beings afterwards. But I wouldn't be upset of toning stuff like down in some of the games. It's just very difficult to create something that fits for everybody.
Women were unfortunately treated like crap way before video games existed, that for sure doesn't make it ok and I agree that we should do everything in our power to make that a thing of the past, I am just not convinced that not showing nudity in games will have a lot of impact on that.
I do think that it's weird that it's usually women that are depicted nude instead of men (or a mix of both). I personally would prefer to watch nude women over men, but it's for sure something that I always found somewhat weird and I guess that's for sure sexism creeping in.
