Zynga’s newest game CityVille has passed 100 million users. The game launched only 41 days ago. Not bad. However FarmVille is has a higher percentage of daily active users as a percentage of monthly active users than CityVille. CityVille has more international users and and a younger user base than FarmVille does, but it makes less money for Zynga than FarmVille does. Despite the lower amount of money and less stickiness for daily users, the growth is still very impressive.
