fwiw I agree with you that eroticism has its place. It'd be a shame if we lost that from the world. What you're not seeing though is the (I hate to say it) bigger picture. If there were as many games aimed at objectifying men for women then as far as I'm concerned no problem. If there was as much media in general that treated men and women the same, whatever than treatment be, then no problem, but that's not how things are and that's the issue. Basically, one game isn't the problem, the volume of games like it is the problem
There's more objectifying men in games than people realize though, we've just been conditioned to not notice or see it as somehow different.
For example there's the men of Metal Gear, Snake has always been sexy, what with his skintight outfit in MGS2 and all that, there's also Raiden who is at one point nude with his hands covering his junk, is that not fanservice for female gamers? And yet with all these sexy men people still raised a stink about Quiet in MGSV, that's a double standard.
Dante in the Devil May Cry series, especially 3, is supposed to be a sexy character.
God of War, a series that (used to anyway) infamously feature topless females also has Kratos always without a shirt.
And fighting games like Dead or Alive, Street Fighter or Soul Calibur feature females characters with perfect bodies but the men are also ripped, take Street Fighter for example, there's Cammy who's known for wearing a thong one piece type gettup, but there's also characters like Urien and Gill, who wear nothing but little thong diapers, even less than Cammy.
Yet remember the controversy over R.Mika's "butt slap" animation?
My point is, a body is a body, skin is skin, a scantily clad male character with a perfect body is not really different than a female one when you boil it down, so why is it only the female ones who are controversial? I, a heterosexual male, have never been bothered by the sight of a shirtless male character with six pack abs or whatever, so it's absurd to me to think of a heterosexual female getting offended over the sight of a scantily clad female character with big breasts.
