The purpose of this unique book is to outline the core of game science by presenting principles underlying the design and use of games and simulations. Game science covers three levels of discourse: the philosophy of science level, the science level, and the application or practical level. The framework presented will help to grasp the interplay between forms of knowledge and knowledge content, interplay that evolves through the action of the players. Few scientists have witnessed such a radical change in their area of research and practice as those who engaged in play and gaming since the 1950s. Since that time game scientists from a whole variety of disciplines started adopting gaming and simulation methods in their research. Rapid advances in information technology and computer science are producing a tool rich environment for the design and use of games, and for humanities studies of games as digital arts and interactive narratives. Game science is advancing through these waves...
