In addition, the games, at least since Metal Gear Solid 2, have also pushed [[nihilism]] and [[moral relativism]] in an implied positive light. The Brandygames guide also mentioned that the series' overall theme was derived from Frederick Nietzsche, specifically his work "The Eternity of the Same."
