Can we not with the "one and done" comments? There's a way to say that something is a great, succinct summation of the answer to OP's question without implying that there's not significant nuance and discussion to be had around the topic. This issue isn't "done" and the question isn't answered until all people feel comfortable and accepted within games, gaming spaces, and the games industry (whether in development or reporting).
I think your point about marketing and audiences is spot on, and perhaps I'm thinking about this in the context of The Sims, specifically TS4, partly because you're at Maxis (though I understand if you don't really have a part in this area of the game or can't speak about it). The Sims has had, historically, a large female player base compared to other games, and I would argue much of its marketing and directions understand that. It is, after all, based on the concept of dolls in a dollhouse. TS4 definitely has rooms to improve (I saw a great Twitter thread recently about how it should have wheelchairs available, though I understand what a technical challenge that might be, for the same reason there's still no height slider), but it has made some real strides in being more inclusive: clothing options are coded as masc or fem, but any body can wear them, and you can select whether your Sim can become pregnant, if they pee standing up, etc. As far as I'm aware, gay and lesbian relationships have been in the series for some time (at least since TS2), as have different skin color options. It is my understanding that the hair options for people of color have also improved a lot in the last few updates and packs. The last University trailer also featured a black woman prominently.
These changes have not faced nearly the same level of blowback or outrage as, say, Battlefield V putting a woman on the cover, at least not that I have seen. I have to imagine that a large part of that has to do with the audience of The Sims and who it is marketed to. One would think similar arguments would arise from camps concerned with "SJWs invading gaming." But I think those people also don't consider The Sims to be a real game for real gamers, so it doesn't fall on their radar. It's all about gatekeeping, about protecting the space they have understood to be "theirs" and being afraid of other, different people (rightfully) challenging their views.
