Diversity in games and movies is similar to using more impressive cameras or better CGI. It absolutely provides the ability to create a better game or movie, but it can't be the only reason you make a movie or game. That's why if you create something to showcase your new thing or technique, it's called a tech demo or a "proof of concept" type thing, not a game or movie. If you make a production whose only point is diversity (or exclusion) you have failed. The only reason it's viewed with all of the rage and passion is because it is another front on which the utterly meaningless culture war can rage, where self-important, self-styled "enlightened" people can make braggadocios claims and performatively declare that this or that minor thing that no one cares about is actually a huge concerted effort by their "opposition" to fundamentally change our society to be worse. I have got news for you my little chickadees; movies and games DO NOT fail or succeed because of diversity. They never have, and likely never will. They succeed or fail on many factors, but all of your huffing and puffing and beating your drum is completely, utterly inconsequential. Conservatives call liberals communists. Liberals call conservatives fascists. The vast majority of people call both groups nuts. I instead wish people would learn what communism and fascism is. Well, not really. I think all of you are nuts too but I still hope that one of you nuts might play a game in coop with me.
