Looks like the pressure is not only on the corporate and executive level. Zynga is closing down Petville and other poorly performing games. Seems like Kixeye and Gree are making a dent into their empire. Or simply that people just don't play those games anymore. The complete list of games being cut are some of the low hanging fruit, which to me, Zynga only created compete with other "better" versions from competition.
