Zynga is canceling CityVille 2, Party Place and The Friend Game

Mobile games developer Zynga is canceling CityVille 2, The Friend Game and Party Place, COO David Ko announced today during the company's quarterly earnings call.

According to Ko, the games, all launched last fall, will be canceled because they did not meet the company's expectations.

CityVille 2, the sequel to Zynga's 2010 city-building simulator, went into closed beta last October, just one month after the launch of Farmville 2. CityVille 2 launched publicly on Facebook on Nov. 1 as a free-to-play title with additional content available for purchase, but quickly lost active users in the following months.

When asked if the success of FarmVille 2 "cannibalized" the audience for CityVille 2, Ko said that Zynga is still learning from its game launches. The company plans to launch fewer titles and space out their release dates in the future.

The Friend Game and Party Place both launched in December of last year. The Friend Game asks Facebook users to answer questions about themselves and in turn asks players' friends to provide answers. Party Place requires players to create an avatar and plan, throw and clean up after virtual parties.
