I'm having de ja vu. These exact same topics started popping up before a big bang and mass migration to Reeeee Era.
Honestly, the game worlds don't always need this shit. Who's going to give a shit whether Ratchet and Lombax is gay, or if Sackboy is non binary or Aloy is a raging gender fluid lesbian looking to ravish the nearest woman who isn't white.
Don't care. If you're in the video game business your first and foremost priority, should be, to make fun games. Because you can put billions into a game that tells the most beautiful story about a gay relationship between two people of different colours and if a game that's far more fun to play like Astro Bot comes out and I have to choose between the two? I go Astro Bot.
If you're looking to games for validation about your gender or identity or whatever, you're looking in the wrong place. If you're looking for representation, you're looking in the wrong place.
Game worlds should be a proper representation of the world as it is. Transgender people are a tiny population, certainly of the global population, so if you overfill your game on DEI check lists, then you aren't really setting out to make a game are you?
Personally it can be done very tastefully. Dion in FFXVI was genuinely a suprise that he was gay, but it changed nothing about the character and his story was very good indeed. Bill and Frank in the Last of Us TV episode was a beautiful depiction of a gay relationship.
And I'd happily play more games with black, female, gay/whatever protagonist inside, providing you make a great game. No issues at all. Should more games like that be made? Probably. A lot of games I love either have female or black protagonists. I don't doubt people can make incredible games like that.
You put love and attention into your character and game world and it'll feel sincere and natural.
