Where is the game grand theft auto san andreas set?

The game takes place in the fictional state of San Andreas, which mirrors Southern California's geography and culture. This includes the sprawling metropolis of Los Santos, a direct analog to Los Angeles, surrounded by rural countryside, deserts, and mountainous terrain. The setting allows players to explore a diverse open world reflecting the varied landscapes and urban environments of the region. While the provided evidence specifically references Grand Theft Auto Online, which shares the same fictional state, the broader Grand Theft Auto series consistently uses this Southern California-inspired locale for its narrative and gameplay.
