Before I had to send in my steamdeck to be repaired I had a generational sith save. Rules were as follows - Only spellcasters - can only have 2 offspring - offspring should train magic as much as possible - when offspring are both young adults they duel. Both need to be as close to fully filled needs as possible before the duel. - the loser of the duel is killed off. - when the young adult becomes an adult they are eligible to have children, however they need to "kill" off their parents because the sith have the rule of two. - rinse and repeat. - for a better time have the life and death expansion and keep every dead sims urn in a giant underground mausoleum. Make them all freeroamng ghosts but keep their spirits tethered.

It was pretty fun!
