The Secret Science of Games is an accessible and entertaining guide to the hidden role of science in making games more fun. User Experience ("UX") research is a vital part of the story of how video games have become a cultural juggernaut, but game developers generally don't speak publicly about how data shapes game design and game development. This book is a friendly and practical tour of games research by someone who's done the work, including true behind-the-scenes stories about how your favorite games really got made.
