Back in June, GamesTM published their preview of The Sims 4. There was an interesting sentence about a potential world in the game:
”We spot a drawing on a nearby whiteboard of a humble rural shack, surrounded by rolling farmland, livestock and mountains in the distance. Could the American frontier be another location in The Sims 4? Truong and his colleagues refuse to comment.”
While going through The Sims 4 Game Files, I saw this Concept Art of the World. It exactly matches with the description that GamesTM gave!
