Call me crazy, but as much as I love GTA SA I had to stop playing it because of the genocide message. The biggest rival gang CJ and his brother Sweet (Grove Street Families, a predominantly black gang) has to kill off the Ballas (another predominantly black gang). I get that the game was set in the 90s, but as the older I get, the more disturbing it gets as I think about it.
And also I know that he kills off the Vagos gang too, but they not affected as a whole like the Ballas, seeing as it still have the Aztecas gang and the San Fierro Mexican gang even after you kill off the Vagos.
