The game is centred around the return of Carl Johnson (also known as CJ) to his gang (the Grove Street Families), and their subsequent return to power.
By far the largest and most complex playing field of any 3D Universe game, San Andreas consists of three fully-realized cities: Los Santos, San Fierro and Las Venturas, and includes vast expanses of countryside, forests, a desert, and even a mountain and many hills. Unlike GTA Advance, which faded into obscurity, Rockstar Games still pays tribute to the critical and commercial success of San Andreas. San Andreas has left a lasting legacy in GTA 4, the DLC episodes, and even GTA Online, as every game since has mentioned it in some way. Rockstar Games continues to reference the highly successful GTA San Andreas game in their future games.
