As the video game industry becomes more and more sophisticated, designers find that players are assessing AI behavior with increasingly humanistic eyes. Why do some games seem "better" than others, even if they're not doing anything more complex? Why do some games feel more "real" than others? Why are certain people attracted to certain game genres, and is there any way that we can expand the audience for our games? These are all questions that require a strong understanding of the psychological issues surrounding games, gameplay, game AI, and the decisions we make in designing our games. THE PSYCHOLOGY OF GAME AI explores the psychological foundations of people with respect to game playing, as well as some crucially important human quirks every designer should be aware of in their quest to craft ever more compelling and realistic games.
