This book is not about sport, but some of what she says about games is applicable to sport. She does discuss, briefly, Suits’ definition of games, so that’s a plus.
Here’s my brief review (Cross-posted at my Philosophyblog and Goodreads).
The most surprisingly thing about this book is that it is many ways a self-help book. It discusses games in the context of how game-playing (and understanding games) can help make one’s life better. In the closing paragraphs, McGonigal says: “Games don’t distract us from our real lives. They fill our real lives: with positive emotions, positive activity, positive experiences, and positive strengths” (354). Much of the book is explaining and defending these claims.
The first half of the book was much more interesting and engaging for me. McGonigal discusses how games affect individuals: their work, their happiness, their relationships. The games she brings in here seemed appealing. It made me want to go and play some of them. Typically the games where not in any way designed with these positive effects in mind; they were just games that had these results.
McGonigal also sees games as a way of changing the world and solving various kinds of large scale problems. This last part of the book was less convincing and less engaging. Maybe it’s because the games here seemed too contrived or the results too unrealistic, I am not sure. But in any case, something was missing in her discussion here that made me skeptical of the ways games (qua games) could be used to solve real global crises.
