'CityVille' now bigger on Facebook than 'FarmVille'
(Mashable) -- Facebook game developer Zynga has proved once
again that it knows exactly what it needs to do to keep millions of
Facebook users happy and occupied.
In less than a month, its latest game "CityVille"___ ______
(become) the most popular application on Facebook, surpassing
Zynga's previous hit "FarmVille" in all areas.
According to AppData, "CityVille" now has 16.8 million daily
active users, compared to "FarmVille's" 16.4 million. Looking at
monthly active users, "CityVille" is also ahead with 61.7 million
users, while "FarmVille" trails behind with 56.8 million users.
Zynga's "FrontierVille" and "Texas HoldEm Poker" also round out
the top five: put those four apps together (we'll disregard the fact
that many of those users overlap for a second) and you have a
very impressive number: 184 million active users across four
games.
The only non-Zynga app in the top five list is "Phrases," _____ at
one point threatened to take the top place, but is now
overshadowed by both "CityVille" and "FarmVille."
"CityVille's" future success wasn't hard to predict after an
amazingly good start at the beginning of December, but it's still
impressive to see Zynga amassing tens of millions of users in a
matter of days, proving that all that venture capital that went into
the company isn't there by accident.
