    They teach you how to make games. This book does not show you how to make games. It shows you how to take your game project to the finish line. Many game projects never make it beyond the alpha state.Game Development Success Is All About The Inner Game.Being a successful game developer does not (just) mean being a great programmer, a smart game designer or a gifted artist. It means dominating the inner game of game making. This separates the pros from the wannabes. It's the knowledge of how to stay focused, motivated and efficient during your game projects. It's the skillset of keeping things simple and avoiding misleading dreams of the next overnight success. Finally it's about thinking as a salesperson, not just as a designer, programmer or artist.

    By 1941, Winston Churchill had come to believe that the outcome of World War II rested on the battle for the Atlantic. A grand strategy game was devised by Captain Gilbert Roberts and a group of ten Wrens (members of the Women's Royal Naval Service) assigned to his team in an attempt to reveal the tactics behind the vicious success of the German U-boats. Played on a linoleum floor divided into painted squares, it required model ships to be moved across a make-believe ocean in a manner reminiscent of the childhood game, Battleship. Through play, the designers developed "Operation Raspberry," a counter-maneuver that helped turn the tide of World War II. Combining vibrant novelistic storytelling with extensive research, interviews, and previously unpublished accounts, Simon Parkin describes for the first time the role that women played in developing the Allied strategy that, in the words of one admiral, "contributed in no small measure to the final defeat of Germany." Rich with unforgettable cinematic detail and larger-than-life characters, A Game of Birds and Wolves is a heart-wrenching tale of ingenuity, dedication, perseverance, and love, bringing to life the imagination and sacrifice required to defeat the Nazis at sea.

    From a vast survey of primary sources ranging from eighteenth-century strategists to modern hobbyists, Playing at the World distills the story of how gamers first decided fictional battles with boards and dice, and how they moved from simulating wars to simulating people. The invention of role-playing games serves as a touchstone for exploring the ways that the literary concept of character, the lure of fantastic adventure and the principles of gaming combined into the signature cultural innovation of the late twentieth century.
