The idea that such pervasive and ever-growing immersion in digital gaming affects gamers real life seems obvious and is the focus of this volume. A wide range of topics was collected under the "Psychology of Gaming" header. The eight chapters in this edited book do not represent all the topics in the psychology of gaming, however, this book includes a variety of topics in this field: game theory, emotional engagement, fantasy world, game designs and development, and gambling with on-line games. This book discusses the psychological impact of games shaping gamers self-perception and self-concept, socio-psychological implications of gaming, design criteria in games, educational uses, the role of fantasy in game play, psychological treatment of gambling-related behaviours, psychological factors of collaborative learning, and gaming as a means of gaining empathy and understanding for another culture.
