"A fact-filled and vitally important book in which top scholars successfully employ evolutionary theory to better understand the causes and effects of digital games." – Patrick Markey, Villanova University, USA"An evolutionary psychology approach is critical to understanding the implicit processes that explain both why we play and how we make sense of play. Play is as natural to humanity as evolution, and implicating these natural processes into models of player psychology stands to deepen our ability to make claims about the experience of video game play." – Nicholas D. Bowman, West Virginia University "An important book that dares to dig deeper. Evolutionary psychology helps us uncover the underlying logics of why people play, and why digital games may (or may not) yield specific effects. Highly recommended for anyone who really wants to understand digital gaming." –Thorsten Quandt, University of Münster, Germany
