Why is casual racism/sexism more accepted in video games than other forms of media (these days)?

Uh.

Coverage and (derisive) commentary from the Western Kabuki podcast: https://westernkabuki.podbean.com/e/gamergate-15/

I know that ILG has been kind of hibernating for the last year on a lot of AAA releases but I've seen some talk elsewhere about the discourse surrounding Stellar Blade, namely that the blatant fanservice and objectification of the main character has gotten a pass because reviewers, at least on the surface, focus on the mechanics/visual performance. I haven't done an exhaustive survey of reviews but I don't think I've seen anyone say more than "yeah, just ignore the jiggle physics, it's a fun game," and as a consequence diminish how regressive its depictions of women are, and that this represents a significant backwards step. (I kind of think the "horny on main" phenomenon might explain why some (male) reviewers are choosing to overlook this.) What do folks think?

I think you've basically covered it. Almost every review takes issue with or makes note of the sexualized outfit and perspective, but notes that the rest of the game essentially does nothing to add to or subtract from that depiction. It's not otherwise a horny game apart from the extremely horny visual depiction.

My understanding is that the character is specifically modeled based on Shin Jae-eun's body fwiw.
