Zynga Chief Game Designer Brian Reynolds Leaving Company

Zynga Inc. Chief Game Designer Brian Reynolds, who led the development of titles including “CityVille 2” and founded the company’s Baltimore studio, is departing from the largest maker of social games.

Steve Chiang, Zynga’s president of games, confirmed the departure in an e-mailed statement yesterday.

“Brian has a long history in the game industry and has been a great partner to the creative leaders at Zynga,” Chiang said in the statement. “I want to thank him for his leadership of the Zynga Baltimore studio in the design and development of ‘FrontierVille.’”

Zynga has lost more than a dozen top managers amid slowing demand for virtual goods and a 75 percent drop in shares since its December 2011 initial public offering. Chief Executive Officer Mark Pincus said in October that he’ll trim 5 percent of staff, close his Boston office, and end more than a dozen titles.

Reynolds founded and led the Baltimore studio known as Zynga East, which produced the game “FrontierVille.” Prior to Zynga, he earned acclaim as the lead designer of Sid Meier’s “Civilization II,” a strategy game developed by MicroProse Software Inc.

Reynolds didn’t respond to requests for comment.

Zynga shares declined 2.7 percent to $2.53 at the close in New York, after sliding 8.5 percent yesterday.
