SimCity is the city in which all of the games in The Sims series are based and is a major city in SimNation.

Many products and services come from SimCity. Buy Mode items are also apparently made there as well. In The Sims, the main stretch of community beach is named "SimCity Beach," implying that Downtown is part of SimCity. In The Sims 2, the newspaper and many city services and agencies are labeled "SimCity", this seems to indicate that the Neighborhood is in or directly adjacent to SimCity. While it is debatable for other neighborhoods such as Veronaville and Strangetown, Pleasantview is definitely a part of the city.
