The Top 25 Facebook Games for December, 2009 -- A Mixed End to a Big Year

Traffic stayed level or fell for most of the biggest Facebook games during December, according to AppData. 10 of the top 25 games saw decreases from December 1, 2009 to January 1, 2010. Another 5 games saw gains of less than 1 million.

We’ve previously seen drops in traffic on this monthly leaderboard. Over the course of November, 8 of the top 25 games had seen traffic drops — but mostly drops of less than 1 million users, whereas this past month almost every game that fell did so by more than 1 million.
