Correct me if I'm wrong, which im sure someone will, but i dont think its a law anywhere. Its story policy almost everywhere. Like gamestop will NOT sell m-rated games to anyone under 17? w/o parents but thats because of store policy. Im 95% sure there is no connection between the esrb rating and actual state laws. And as this case shows, its totally unconstitutional to legally restrict us from games, but businesses can do whatever they want.
