[Every other week, Gamasutra examines the most popular Facebook games according to monthly active users, looking at the top titles and developers on the social network to see who's attracting or losing players.] Omgpop and Zynga's Facebook app listing for Draw Something (the mobile versions hook into the social network's API, so it shows up AppData's rankings as an app) is still picking up users, but it's no longer bringing in several million new players a week like it was for the past month. Draw Something gained about 800,000 new monthly active users in the last week, and is now up to 33.2 million total. It still has the biggest daily audience for any Facebook app with its 14.3 million players, but it's been stuck around that mark for weeks. It's beginning to look unlikely that Draw Something will surpass the most popular game on Facebook, Zynga's CityVille, any time soon. That title, though, has lost 1.2 million monthly users in the last two weeks, and is down to now 43.7 million.
