GTA IV and its DLCs were the starting point of Rockstar's realism in GTA V. The driving, the police, the Wanted Level system, the shooting, etc are more realistic. The minigun was removed from the game due to realism. In GTA IV, you can die fast too but GTA V is way worse. GTA IV and V lack a lot of San Andreas and Vice City's activities due to realism, and were replaced with more realistic ones such as Yoga, Darts, Pool and Tennis.
