There have been several neighborhoods made by Maxis and Electronic Arts for The Sims 2, The Sims 3 and The Sims 4 that were never released to the public. Riverside and Waterside were used in previews for the pre-released The Sims 2 but never released, and a third neighborhood named Sedona is referenced in game files. Two versions of Sunset Valley were made but due to the delay of the release of The Sims 3, additional changes were made.
