Cityville beats Farmville on Facebook
When Cityville was released, it got over 60,000 users within the first 20 days. As of today, Farmville has a total user count of 13,357,004 and Cityville has raced it with 16,778,004 online users.
The sudden popularity of Cityville could be attributed to the fact that developers worked on it for over a year before making the game public. Also, it was released in 6 international languages. Compared to these factors, most other facebook games are released with just a few months of developments and usually in just one language (en). Cityville is also gaining a lot of new users via its website and not just via facebook.
