Zynga has filed a lawsuit against Alan Patmore, the former general manager of the company’s CityVille game that left to work for Kixeye, a rival Facebook game making company. Zynga alleges that Patmore amassed 760 documents that could “improve a competitor’s internal understanding and know-how of core game mechanics and monetization techniques, its execution and ultimately its market standing to compete more effectively with Zynga.”
