All of this is distinction without a difference, imo. It's like saying female authors, who write about tentacle rape of men(who learn to love it) in m/m novels are fine in doing it, because there is a clear motivation behind it... it doesnt matter what the motivation is, at the end of it all you wanted to write a romance novel about Stockholm tentacle rape. These people are creating these motivations to have a sexualized desire objectified. You are being strangly obtuse if you dont think this is the case.
Nobody is forcing them to write the woman in this was and nothing of true value would be lost if they didnt do it. That isnt to say that cant or they shouldnt objectify their sexual desires in video games, but it doesn't make it something more then what it is. The character can have all the motivations in the world to want to show her assets, and thats fine, but trying to make it into the idea that they weren't written that way, because of a certain enjoyment from sexual gratification, I find to just be a bizarre form of denial.
Nothing inherently wrong with wanting sexual gratification, but the game industry, imo, does it in a fashion where it comes across as disingenuous(as in pretending they dont mean to do it or "I isnt about us liking sexy things"). If you want to sexify your game, that is fine, honestly. However if people who like a certain genre are getting sick of or annoyed with the constant eye candy, it isnt really much of a big deal for people to voice their concerns and imo is helpful, cause the game industry from a narrative perspective, imo, has a long way to go and minimizing distractions, to me, would help.
I'm not one who personally has issue with sexual objectification in general, maybe it's cause I swing both ways, I dunno, however I find video games(And most literature if I'm being honest) sexualization to normally be more silly and dumb more so then attractive.
