@Amapola76 I decided against including Strangerville because I stubbornly wanted my sims to be near a metropolitan area, whereas Strangerville is in the middle of nowhere and not really matching any of the other worlds. But maybe I can make over Del Sol Valley to function as the closest city. Strangerville would certainly give my sims (I plan to start with four and then recruit allys) plenty of backstory, with the military base, the science lab and the ranches all using their own model of robot/android. I'll have to think about this some more.
@Lenny_Ogg I love the glowing toxic waste in your second screenshot! Will definitely have to include this now in one of the lots.
