I posted this last month, but it seems relevant.

After the normal "bizarre landscapes, horrifying situations" style of play I decided to try playing through Sims 2 with a normal, happy, and healthy family of Sims. 1950's businessman-type and his stay-at-home wife, with their 2.5 children and an actual white picket fence.

However, I kept achieving various family goals, and getting rewards, and I built up a stock of the elixir of life water coolers. I only fed it to the parents, and eventually their children grew up and moved out, while they kept having more. I built new lots and new houses for their children. They marry the generic supplied Sims in the area, procreate, I play through their lives from time to time, but always return to the original family, keeping them young, moving their kids out.

Fast-forward a few months and I've got this sprawling Sims community full of the most bizarre horrors the combination of added content and the Sims own demonic AI can come up with. At the center of this vortex of horrors of ghosts, vampires, zombies, werewolves, aliens, and college life remains this brightly lit well-ordered lot, with a kindly young Norman Rockwell family living there. The kids change, but mom and dad are just as wholesome and youthful and happy as the day they met... twelve hundred years ago.

Norm and Norma are the Adam and Eve of a millennia-spanning eugenics program, the immortal god-emperors of this expansive and twisted domain. Behind the facade of their wholesome 1950s lifestyle is the fact that Norma is brood-mother to over two hundred young. Norm's eyes have seen the birth, adolescence, aging, and ultimate decrepitude and death of children, grandchildren, and great-grand-children. His drinking buddies are ten-generations-distant descendants of him. His newspaper is delivered by his great-to-the-twelfth-degree grandson.

Until I lost it all in a hard drive crash, all I had to do was occasionally introduce a new family to be consumed by the maw of madness I'd created, and tend to Norm and Norma as they spawned ever-successive generations of family, their unholy brood spreading outward to what I envisioned as total galactic conquest.
