If you thought FarmVille was popular, get this. It's taken just 8 days for Zynga's new CityVille game to attract 6 million daily active users, making it the fast growing game the company has ever released, TechCrunch reports .
As a point of comparison, it took FarmVille 46 days to hit 6 million daily active users and FrontierVille 32 days. After 24 hours had passed, CityVille was inhabited with 300,000 players, and 3 million after a week went by.
Unlike FarmVille and FrontierVille, however, CityVille is the first game Zynga ever released on an international level. CityVille debuted in five languages, including English, German, French, Spanish, and Italian, and benefited from a bigger marketing campaign than either of the two other titles.
