I guess I'll be that guy and plug a lewd mod. Carnalitas Slavery Expansion is pretty unbalanced but also great for RP if you have the self control to not abuse it. For sadistic and/or lustful characters it basically eliminates stress as a mechanic, and if you go wild with enslaving people you never have to worry about money, so you need to either have self control or not give a shit about basically cheating. But from a purely RP perspective, it adds to the Genghis Khan vibes -- "“The greatest happiness is to scatter your enemy, to drive him before you, to see his cities reduced to ashes, to see those who love him shrouded in tears, and to gather into your bosom his wives and daughters.”
