I doubt anyone's still on here, but I had an interesting idea.
Make one female sim with striking characteristics (i.e. firey red hair, ugly, insanely pretty, etc.)
Move her into every single house (either in one specific town or in every town you own)
Have a child with every man able within the household. While you're pregnant, build the family a new and improved house, and makeover all the townies that live there.
Every time you move houses, you need to bring your children with you unless you have a husband. Said husband must stay at a house you built with female sims' money. He can raise some of the children you have with the townies. No money cheats or taking money from the families you stay with.
Eventually, you'll have SO many children, and the town will be overwhelmed with them!!
