the secret to including trans people in your game is to make a 100% normal game with no trans people in it
then 3 months after release you hit them with the ol' JK Rowling
"Geralt was trans the entire game and you never realized it. He's completely confident and fulfilled in his new body, and everyone sees him as and treats him as a man. We did not address this in-game for the obvious reason of deadnaming, and because it's not relevant to the male self Geralt expresses now. We also thought it an appropriate twisting of the knife to reveal this fact now to bigots everywhere: you were playing as a trans character all along.
Cheers and stay Witching."
