SIMTROPOLIS
Simtropolis is a medium sized world, consisting of four districts. The districts include Simtropolitan Square, New Old Town, Strangeburb and Little Veronaville. It is set 25 years after the Sims 2, 50 years after the Sims, and 75 years after Sims 3. It includes recurring families, such as the Goths, the Monty's and Capp's, the Curiouses, the Landgraabs, the Pleasants, the Calientes and the Grunts. There is also a secret island with a mountain, called Mount Monolith, which houses the golden home of Father Time, his wife Mother Nature, their teenage son/daughter Mystery Sim, and toddler son New Year, and the snowy home of Father Time's brother, Santa Claus, his wife Mrs Claus, and their children the Elves.
