Cheats in Grand Theft Auto: San Andreas are similar to those of its predecessors, requiring input of a series of controller button commands or a keyboard. When a cheat code is successfully entered, a "Cheat Activated" message will appear on the upper left corner of the screen to confirm the cheat has been entered. The following cheat codes must be entered during gameplay. Entering cheat codes during pause menu will not activate the cheat unlike its predecessors.
Rockstar released two follow-ups to San Andreas: Grand Theft Auto: Liberty City Stories and Grand Theft Auto: Vice City Stories, both by Rockstar Leeds. Unlike San Andreas and its predecessors, Liberty City Stories and Vice City Stories were developed for the PlayStation Portable handheld, and there was no Windows or Xbox version although a PlayStation 2 port was released afterward.
Liberty City Stories and Vice City Stories are prequels to San Andreas's predecessors, so both games derive their maps from Grand Theft Auto III and Vice City, respectively, each of which cover a considerably smaller area than San Andreas. Liberty City Stories and Vice City Stories eliminated gameplay elements introduced in San Andreas, including the ability to swim (in Liberty City Stories, but reintroduced in a limited capacity in Vice City Stories) and climb. Both Liberty City Stories and Vice City Stories include references to characters featured in San Andreas, with Liberty City Stories set about 6 years after the events of San Andreas (in that game, for example, radio reporter Richard Burns, featured in news bulletins in San Andreas, returns as a radio call-in guest) and Vice City Stories set about 8 years before the events of San Andreas. Except for news bulletins, radio programming in Liberty City Stories and Vice City Stories does not change based upon player progress. While character customisation elements such as wardrobe changes are retained, for later games, Rockstar eliminated the need for the game protagonists to eat and exercise.
San Andreas marked the technological pinnacle of the Grand Theft Auto III era (also known as the "3D Universe") and also the end of that continuity (albeit for the handheld-focused Liberty City Stories and Vice City Stories spinoffs). Rockstar launched a new canon (the "HD Universe") with Grand Theft Auto IV and Grand Theft Auto V for the seventh-generation consoles. The celebrity voice acting that had been so prominent in the "3D Universe", especially in Vice City and San Andreas, was scaled back in the "HD Universe". Rockstar also took a new direction in the series, focusing on realism and details instead of greater area and added content. For instance, although the exploreable sandbox area is smaller than San Andreas, the main setting for Grand Theft Auto IV is comparable to San Andreas in terms of scope when "the level of verticality of the city, the number of buildings you can go into, and the level of detail in those buildings" are taken into account.The goal for the HD Universe layout of Liberty City was to have no dead spots or irrelevant spaces, such as the wide open deserts found in San Andreas state. Ars Technica wrote Grand Theft Auto IV's "slight regression of the series from Grand Theft Auto: San Andreas is surprising: there are fewer vehicles, weapons, and story missions, less character customisation, and even the size of the city itself is smaller
