No explanation was given, with the company saying in an SEC filing that the resignation was "not tendered in connection with any disagreement with the Company on any matter relating to the Company's operations, policies or practices." Then it was Chief Creative Officer Mike Verdu, who left in late August to start his own company and Alan Patmore, general manager of CityVille, who left to work at Kixeye. Erik Bethke, general manager of Mafia Wars 2; Ya-Bing Chu, a VP in Zynga's mobile division; and Jeremy Strauser, a general manager have all left as well. Add to that the accusations that Zynga executives and investors engaged in insider trading when they sold their stock months before it crashed, and the lawsuit from Electronic Arts, who claimed that Zynga had plagiarized EA's signature game, The Sims Social, with its new game, called The Ville. Zynga stock is currently up over 4%, trading at $3.21 a share, a far cry from its $10 IPO price in December.
