Keep in mind that games have this problem tenfold compared to other media, only comics come somewhat close and in that case it's mostly superheroes. It's not even just about realism per se, there are plenty of unrealistic games where that kind of objectification feels very out of place and I've always found weird that stuff that would normally relegated to a 70s sex comedy is the norm in games across multiple tones and genres.
Mind naming some examples from the last decade? Because seriously, it's nowhere near as much of a thing as you're implying it is. Fighting games mostly use the same ridiculously overstylizied and sexualised design that superhero comics do. And they do it for men too.
Because I really can't think of that many examples that would be out of place in a Michael Bay-style summer blockbuster. Or any anime, really. So this "problem" has almost nothing to do with games as a medium. I think it comes from this weird desperate need for your medium to be taken seriously by old people who don't care about it. That and people being massive prudes.
So every game needs to be super serious to compare with other "serious" media even though almost nothing you'd find in games would be uncommon in either summer blockbuster or schlocky B movies.
And some people seem to confuse "sexualised" with just plain "sexy". Because even if your character is sensibly dressed for the situation god forbid she's actually attractive because that's just objectification.
If you're constantly blasted by sexualisation in your games then stop playing cheap "double A" Japanese games because that's pretty much the only place where you'll find it nowadays. And that's thankfully not changing any time soon.
Unless you think showing some leg or midriff with clothes that normal people normally wear in the summer is "oversexualisation" and that we should all go back to the Victorian dress code.
