There is no left-wing conspiracy to take your sophomoric video game tropes away from you. Norms have changed pretty rapidly in the last 10 years, I would argue mostly for the better , and there are admittedly many who can be obnoxious about enforcing them. But the changes in game content that you're complaining about are primarily driven by market forces:
- Video games are no longer the domain of primarily male nerds. It's a major entertainment industry catering to an increasingly diverse market. Nearly half of gamers are women. Soon most will be people of color. As the audience shifts to demographics with less patience for casual misogyny and tokenism, the product content will inevitably follow. If women gamers aren't as into playing games with avatars catering to male sex fantasies, it's not a conspiracy when boobs shrink and shoulders start getting covered.
- As the game industry has grown, it has also attracted more diverse talent. More women, people of color, and members of the LGBTQ community now work in the industry. Naturally, their perspectives and preferences are increasingly reflected in the content of the expressive works they help develop.
I would also add that as games have become increasingly narrative driven, and as you get better, more advanced narrative writing, you're inevitably going to encounter more "politics" in your stories. Art informs our humanity. It can also entertain, sure, but good art seeks to help us understand something about the world we live in, even if on a surface level it's a story about aliens, or wizards. Lord of the Rings was a reaction to WWII; The Matrix is a retelling of Plato's Allegory of the Cave.
Maybe there is a good story to tell about how modern men are being emasculated and their biological imperatives suppressed by women and minorities who are just redefining mores in order to grab power. But I've got a secret to tell you: good conservative artists are pretty rare, which is the main reason you don't see, for example, good conservative cinema. Sean Baker made a great movie about trans hookers on an iPhone; Trey Edward Shultz made a great movie about familial trauma with 30k and a bunch of non-actors. There are no gatekeepers to making and distributing movies, books, and games to a mass audience the way there used to be. And yet...
