When people would realise how mankind works for like one million years and that everythign is sex related after being grown up, then they may finally understand that sexualisation is a vital part of both genders.
sexualising women is as much in our nature as sexualising men. Yes women do this too.
And since gaming is mostly done by guys the sexualisation of girls is of course more present.
This picture is quite close to the truth and it does not only sexualise the women. The amount of womens who react to exactly that kind of man is also very high. They just don't let that knwo everyone so openly as man do it when they see a sexy female.
The whole discussion is just senseless. Both sides have their fantasies, and most women even forfill these fantasies for their man/boyfriends. Because they also like to be sen as sexy. And when man go lifting they also do it because they know women think its sexy. And most women do like and react to that too.
And of course in mostly male genre games you will see more sexualised womens. Because it addreses males.
And the harassment part? Thats hardly truly gender related. People in the internet harass each other anyways. They just take the first thing they find. And this is usually "eeew ist a gaming girl". And lets be honset if it wouldn't be that, they would just use something else.
If designers want to change something, they should make more games adressing girls. But since they are a lower Playerbase, they are less profitable. Maybe in some years when the new generation is grown up this differs since todays girls are also consuming a lot more time in front of PC's and consoles.
