Top 25 Facebook games for February 2010

ISG has rolled out the Top 25 Facebook games list for the month of February. FarmVille is still leading the pack -- no surprise there -- with 83 million monthly players, and Cafe World is still the second most popular game on Facebook, with Zynga's Texas HoldEm Poker in a close third.

Happy Aquarium and FishVille seem to be having a hard time staying afloat, both losing players over the past month, and PetVille finally manages to overtake Pet Society as the #1 pet simulation game on Facebook.
