Whoa there, cowboy.
Do not lump me together with her. Although I agree with a lot of what she says, I don't place full blame on gamers. And, as people have clearly stated, her research has fundamental flaws and she's definitely lost some objectivity with some of the things she said.
As I said before, I mostly blame lazy storywriters and game producers.
For a storywriter, It's EASY to use that trope. The princess becomes the horde of bananas we gotta get back. If you can replace a character with an equally-beloved pile of bananas, your storywriting needs work. Mario games are totally guilty of this. They're still great games, though.
And it's easy to say, as a producer, something like "Well let's look at the demographic. Hmmm... 18-35 year old males? Research shows they like guns, tits, and blood. If you want a game to sell make it have these three things. What have you got for a plot? Oh, that again? Well just put something that'll make the game sell, will ya?" in a Cave Johnson voice.
Kid Icarus Uprising doesn't have its entire driving point as that trope (though it does happen more than halfway through the game).
People really need to read all of what I type, and not just every sentence that grinds their gears.
I go back to the original statement that it's perfectly fine to enjoy a game, while at the same time being critical of the aspects of society that it portrays... or something. I can't quote 'cuz it's quite a few pages back, blah.
