@aprrrl@witches.town Dunno if you've read the Ancillary series, but one of the primary cultures in it doesn't have gender. In one of the books, a character from another culture asks "but how do you have kids??" to which the very sensible reply was "You go see a doctor and get the necessary adjustments made."
@aprrrl@witches.town Anyway, the trick with writing alternate rigid gender roles is to make sure the players parse it as gender and not as caste or something.
