It isn't just games though. It's pretty much and type of information media that get's across to us. It's called human behavior. As a social species, our inherent instincts and reactions are to want to bond with our environment and the people around us. Commonly accepted information medias help bring us together. In short, it helps us to feel accepted and fill a niche in society. Or I'm just spouting bullshit. With me, you can never tell (much to the chagrin of my family).
