Quests to add NPC's?
I am building an eternal kingdom, and am trying to make it the most perfect and filled kingdom. I have all my sims have 4+ kids to fill the world with kids, and I'd like to fill the world with adults as well. I know certain quests will bring new characters into the world permanently. I've been planning on making a list of quests that will add people, but I'm wondering if someone has already done that?
