I feel guilty sometimes when evicting most Maxis Sims from a new Save and deleting a lot of those "not in world" that Maxis make, especially those with peculiar names. Then I fill my lots with all my own from My Library. I've done all the drowning and killing and got it out of my system from "The Sims onwards" and now try to keep them alive.
The game has a nasty way of aging and killing them all off whilst I rotate families without my adding to the chaos. Maxis are the killers!
