In Game Morality
You can only create heresies in this game. The underlying good/bad always stays the same. You can have cheating being acceptable with polyamory with a target that is 95% into the seduction suddenly shut it down, just because it is breached.
This would not occur in a society if the tenants actually mattered. They’d be encouraging it.
No matter what you do, you get Christian morality as the base setting.
Edit: this essentially goes for every religion. Nothing in game really acknowledges the society functions differently.
And, people sleep on polyamory. Essentially unlimited cost free people that arm known to be yours, which is the most valuable resource in the game.
Combine it with chivalry (French) and personal scheme buffs and it’s a renown printer.
