Well, when marketing leads to a Super Mario game where you can play as peach, she dismisses it as not really counting.
When the same marketing causes a female protagonist to be replaced by a male one, it suddenly counts.
You do realize that in Super Princess Peach, her special power is her Super-PMS? She literally invokes violent magical mood-swings to kill enemies and solve puzzles. Yes the idea is ridiculous, and could be funny if not for the fact that this is how they choose to portray the
only female hero of the Mario series. Really now.
And honestly the only weak points of her discussion on videogames that I can find has to do with marketing and narrative structure. With marketing where she often doesn't understand why certain things panned out the way they did (for reason completely unsexist) and for narrative structure she often puts characters into victimised roles when their roles were dictated to them just by how a story is told.
Isn't a story that relegates its major female characters to victimized or disempowered roles kinda, er, guilty of portraying its female characters as disempowered and/or victims? Like, tautologically speaking?
I'm not trying to be snarky here, I just don't get how that makes for a weak point. I mean, I played Wind Waker too, and I really liked Tetra. And when I played it, though I didn't have words for disempowerment at the time, but I remember being disappointed when she stopped being a Badass Pirate Captain, and got turned into a princess, and was effectively booted from the heroic quest. I mean, her bravado, snark, and guile made her awesome... but that all disappeared when she was turned into a demuring froo froo magical girl. And that's kinda the responsibility of the writers, yeah? I mean, this isn't a result of random events or the player's will or whatever, this is the content creator's choice in how to portray her, and the end result of the story.
The same thing happens to the Bird Girl in Windwaker (I forget her name >_<
when magic and prophecy force her transformation from lovable and bumbling action hero to distant supportive role for the Hero-dude, as she is forced to become a Sage for the rest of time.
And hell, don't even get me started about Metroid and Samus! I liked Samus Aran because she was a badass space bounty-hunter. Her talents and badassery were what was core to her identity, and the fact that she was also a woman was an incidental background detail. Though of course the devs still shoehorned their fanservice in as easter eggs and whatever, her general appearance wasn't sexualized at all, which is still a complete rarity in the industry.
...and then, motherfucking Metroid: Other M happened... "MoM." Samus put in a wet skintight catsuit, wistfully sighing every 5 minutes about babies and bottle-ships and shit. Getting distracted by thoughts of her handsome and square-jawed Commanding Officer on the battlefield, whom she becomes increasingly dependent on. Complete fucking bullshit. That's not the Samus I remember.
So yeah, sexism in games is real, it can ruin good characters and stories, and does not lend itself to furthering gender equality.
