Re: Least violent GTA
Asking for a GTA without violence is like asking for cookies without sugar and made without flour.
Outside of the missions, GTA can be as violent or as peaceful as you want. You can perfectly get around the game, driving "normally," and doing plenty of other side-things that aren't violent. However, the game practically "coaxes" you into being violent with it, since there are plenty of things that scream "its a game! do what you what!"
Play Bully if you'd rather have a game without all the guns and killing.
