The social problem of violence is an urgent topic of many public debates for many years. The problem of displaying violent content in the mass media has been shaped through history in television first. Later, due to technological advancements, it has expanded towards video games and the internet. In my thesis I researched the significance of game theory throughout different historical periods and significance of video games as worldwide media today. In my work I present a number of studies focusing on violence and video games and expose lesser-known features of video games.
