Has anyone accomplished the Legendary Legacy achievement?

Due to culling none of my progress counts -.- i've had over 40 sims, i'm on 5th gen but my original sims are dead and erased from the game, the legacy counter is still at 0 and i am very very angry about this

That is what I am afraid of. I don't know how some people manage to complete this. If the only way is to do a baby factory and not really play, well, I'm not interested in that at all. I also should not have to use mods in order for the game to function properly.
