So in addition to the multiple gay and lesbian couples and multiple nonbinary characters who all exist without comment or fuss in the world, and your own ability to choose a body type and pronouns on character creation, Temtem has a transmasc character in the building where you can change your own name and pronouns, sitting with his father.
Yeah, that's right, canon transmasc character with a supportive parent, getting to just exist in this world. I need to go have some Feelings.
