Hello all! I've downloaded a custom world called Strangetown for the Sims 3, which is a recreation of several forms of Strangetown as seen on PC, DS, GBA, and PSP. The world is amazing and aesthetically pleasing; it gives me the vibe of a town where they'd do nuclear testing in the '50s.
The world was created by aaronrogers8i3, and if you'd like to download it, you can find it here.
