Grand Theft Auto: San Andreas Stories is a supposed video game of the GTA series rumored in 2007 by Latin American blogs, which would be developed exclusively for the PSP. According to rumors, the game was canceled due to "hardware and storage limitations".
In 2013, the Little Jimmy channel took the lie to YouTube, which caused many media specialized in video games to declare it as a fact. However, 4 years later, its existence was partially denied by ElVicioMan who contacted people from the GTA United States Fandom, who had never heard of it.
By not being completely denied by Rockstar. There was never an official clarification from Rockstar about it at that time, so it is still believed to be taken as real as some consider it a Rockstar secret that they never revealed.
