Quote from the OP:
Additionally, a selectable protagonist isn't representation because to avoid a ridiculous amount of work, it necessitates "gender-neutral" writing, and writing that is "gender-neutral" is actually just male-centric. Let's consider Odyssey specifically. Ancient Greece outside of Sparta was kind of hideously sexist, yet Kassandra's gender is never remarked upon, even when it really should be: For example, women competing in the Olympics wasn't just illegal, it was punishable by death - and you even get a sidequest dealing with that very subject... WHILE PLAYING AS KASSANDRA, A WOMAN WHO COMPETED IN THE OLYMPICS AND NO ONE SAID BOO. It breaks immersion completely and makes no sense. At the same time, Greece has a number of important, revered mythological and religious figures who are women, so the intersection of that and everyday sexism would have added a fascinating element to Kassandra's story.
I'm not saying I want Kassandra to have been treated like shit, called a bitch and a whore and threatened with rape every five seconds. However, considering that AC does tackle social issues, often with the subtlety of a sledgehammer (Syndicate's tagline was literally "Oppression Must End"), it seems extremely weird that her gender is never even remarked upon. She could have been an Atalanta-like figure, overcoming sexism and being badass despite being shit on by society. And that's where the "male-centric" writing complaint comes in: having your gender ignored entirely is a luxury only people who aren't oppressed because of their gender (i.e. cis men) are afforded. In that way, playing Kassandra doesn't accurately represent the female experience. "It's a power fantasy!" Sure, but you know who else is a power fantasy? Aloy. Just like Kassandra, Aloy is strong, smart, pretty, gets hit on by almost everyone she meets, and is cooler than everyone around her. I love her for it! And Aloy's gender is kind of really important in how it shapes her story and how the world around her reacts to her. Kassandra may be "canon", so why does it feel like the game was written for Alexios, and then she was hastily shoved in for diversity points?
Kassandra is still written like a man, because it takes to much effort to writte two different chracters, so both chracters are written for a male character,
but one character has a woman skin on.
