I mean, it's mainly about intention, of course. You can have different practices for different societies. But I do want to make the game something that players can relate to, since my intention is for the player to have a good time playing the game, and not necessarily be reminded of things that aren't so great in real life. That's usually what decides a lot of what happens in the game.
Of course, there's a place too for building a 'different universe' with its own set of rules, and I do certainly try to do that with LD+ where it fits.
Certainly an interesting idea with the quest! I'll think about it. Mostly I'll be thinking about what would be the most fun for the player.
