These are the areas added to the game so far. More areas might be added in future updates.
The SimTown Hospital was the third and final Professions career added to the game. Players help two Sims in the Medical Staff career to unlock, build and upgrade workstations from level 1 to level 20. Sims can level up to 10. To get the Hospital players must build the SimTown Express and complete the quest.
Three more home lots in high rise buildings! Complete the Sims and the City quest to unlock and build penthouses.
Recently added to the game in the Downtown High Update. Unlike SimTown High on the mainland, this is an interactive second High School. Build it and complete the Teacher's Pet quest to build more rooms.
