Ender’s Game, by Orson Scott CardRead about the other entries on the list.
When it comes to books about games, Orson Scott Card’s fantastic military science fiction novel is hard to beat. This isn’t your typical gaming book: the stakes are enormously high for Andrew Wiggin and the rest of humanity as they face extermination from the alien Formics. Ender is sent to the military’s Battle School in orbit, where he undergoes a rigorous training cycle on a war simulator, intended to prepare him to lead humanity’s fleet. Even as he’s an unwitting player a larger game, one that will test him to the limits, he must cope with another type of game: a virtual reality fairy tale exploration of his innermost psyche.
