what city is gta 5 based on

Los Santos is the fictional city in the GTA universe, loosely based on Los Angeles and other California Coast cities. It is the setting for games like GTA SA and GTA V, and has many different sections, based on real-life places. Many places are parodies, such as the Vinewood sign, which is parodying the real-life Hollywood sign. Los Santos is the most detailed city in the series, offering tons of activities and places to take part in. Practically all of the sights in Grand Theft Auto 5 are based on real locations in Los Angeles and the surrounding areas of California. While San Andreas is somewhat based on Southern California, GTA 5 predominantly features the urban sprawl of Los Santos, based on Los Angeles.
