People who spend hours playing video or online games are often maligned for “wasting their time” or “not living in the real world,” but McGonigal argues persuasively and passionately against this notion in her eminently effective examination of why games are important. She begins by disabusing the reader of some inherent prejudices and assumptions made about gamers, such as that they’re lazy and unambitious. Quite the opposite: McGonigal finds that gamers are working hard to achieve goals within the world of whatever game they are playing, whether it’s going on a quest to win attributes to enhance their in-game characters or performing tasks to get to a higher level in the game. Games inspire hard work, the setting of ambitious goals, learning from and even enjoying failure, and coming together with others for a common goal. McGonigal points out many real-world applications, including encouraging students to seek out secret assignments, setting up household chores as a challenge, even a 2009 game created by The Guardian to help uncover the excessive expenses of members of Parliament. With so many people playing games, this comprehensive, engaging study is an essential read. --Kristine Huntley --This text refers to the Hardcover edition.
