The thing is, while it's true there are sexed up male characters who are attractive that pop up from time to time, there certainly isn't an 'expectation' for them to be attractive.
By which I mean, for every one handsome charming hero there are about ten ugly muscle bound hate ridden psychos, faceless space marines in body concealing armor and non human aliens.
But meanwhile no matter what, female characters are always attractive and sexed up to some degree. There hasn't been an action game yet that I can think of where the female lead involved isn't some kind of sexual fantasy. In Mass Effect we never see any females of the aliens races that are very non human looking, and all the women are hot.
I dislike it because while we put a LOT of emphasis on making the female characters look sexy, the main mindset of making a male character is just to make him 'look cool' which isn't really the same thing. Grunt from Mass Effect looks cool, I wouldn't want to have sex with him. Masterchief looks cool but you never even get to see his face, Kratos from God of War looks cool but he's ugly as sin.
But female characters don't really get that. In their pictures they are always posing in a sexy way and they are always attractive to some degree. They aren't trying to look strong and powerful in design as much as they are trying to be made to look hot.
Hence why, even though it was really nice to hear that they were finally going to give femShep in Mass Effect her own trailer, it was ruined by Bioware proudly saying:
"And she's gonna be hot!"
Because, really? This is supposed to be a big moment for being much more accepting of your female audience and instead of saying she'll be AWESOME you just say that she'll be sexy. Which sounds like you are trying to use her looks as a selling point.
This trope isn't just in games either, you find it movies and comic books. Take X-men for instance, how many unnattractive aged female characters with very 'unsexy' powers can you think of? Not many I'd wager and I've certainly never seen any in the movies. They are all petite and young and hot women with perfect bodies and beautiful faces and their powers are always attractive on an aesthetic level.
But the men? Green guys with giant slimy tongues? Red scarred faced demon guys with pointed tails? Big blue furry guy with an animalistic face? Plus, some of them are a lot physically older like Magneto and Proffessor X. There are a few attractive male leads in X-men such as Wolverine and arguably Cyclops... but the fact remains that while all the female leads in the X-men movies are beautiful, that same rule doesn't seem to have to apply to the men.
In essence what this kind of jarring line does is create an unpleasant standard:
Male characters CAN be attractive from time to time.
Female characters MUST be attractive ALL the time.
I have nothing against the fact that there are attractive female characters out there, nor the fact that there are unattractive male characters. But it would be nice to see some reversal happening from time to time.
Next time have a male protagonist who is very handsome.
Then have a female protagonist who is unnattractive.
I don't mind having sexualized characters in games, but it really does bother me when practically every single character of a specific gender is made to be either a sexual fantasy or at least an attractive girl next door type deal, whereas male characters can be ugly and monstrous and faceless as much as they want.
