Zynga's new game, CityVille, has just achieved the seemingly impossible.
In just a span of a little more than one month, CityVille - a game about managing a metropolis - was able to eclipse its older sibling in Zynga's family of games, long-time #1 Facebook game FarmVille, to become the new leading application in the popular social networking site.
The game was announced by Zynga on November 18, 2010, but its Facebook launch date was delayed to around December. Nonetheless, CityVille went on to attract more than 290,000 players on its first day online.
