Part 1: Why Games Make Us Superbetter

1. The one billion number is a calculation based on my aggregation of more than twenty global game play demographic and marketplace reports, including the 2014 Entertainment Software Association’s Demographic Report and Newzoo’s 2013 Global Games Market Report, which estimates 1.23 billion active video game players worldwide. That estimate includes 192 million in North America, 446 million in Europe, the Middle East, and Africa, 477 million in Asia, and 116 million in Latin America.

Chapter 5: Challenge Yourself

1. Although players do report sometimes feeling frustration, anger, and sadness during game play, they also report that the “pretend” context of game play creates a safe environment to practice controlling or changing these negative emotions. A good summary of this phenomenon is found in Isabela Granic, Adam Lobel, and Rutger C.M.E. Engels, “The Benefits of Playing Video Games,” American Psychologist 69, no. 1 (2014): 66–78.
