Westopolis (Sonic Adventure 4)

 Westopolis is a major city located in southern California in the Sonic the Hedgehog series. Sonic Adventure 4 marks Westopolis' second appearance in the series after Shadow the Hedgehog, which came out in 2005. The new rendition of the city goes much more into detail, and gives it the feel of a living city. Westopolis is based on Los Angeles, California and its greater metropolitan area. Westopolis is a play on words, meaning "City of the West," which Los Angeles is also called.  Like its real-life counterpart, Westopolis is a huge and sprawling metropolis with various different cultures, ranging from the prestigious film-making industry of Sallywood to the suburban hood life of Glockton, just to name a few. The time and date of the city is about late 2014, around a year after the events of the previous game.  Westopolis serves as the County Seat of Westopolis County, the most developed and populated county in southern California.
