Well a game cant be violent, But it can alude to or display violence. Sensitive to blood? Gore? What about headshots?Should Saints play video games that are mature rated or games that are focused on shooting?
If you play violent game everyday none stop your mind going want to do things that the person doing in the game.
I don't think it's okay to play violent games every day, but once in a while is fine because maybe you might want to do what you did in the violent game
