Throughout this book, I use the phrase “video games” to refer to computer-mediated games of all types, from World of Warcraft to Words with Friends. This may be a more general usage than a purist would select, but I use it because it’s a conventional and recognizable way to distinguish this subtype of games from other forms. I use the term “games” to refer to the broader class of experiences that includes video games as well as board games, sports, card games, gambling, and so on. A more robust discussion of what it means for something to be a game or a video game is found in Chapter 2. See Defining Games.
