FarmVille: Biggest Online Game Ever

If you're on Facebook and have yet to discover FarmVille, a real-time strategy-lite game that lets you plant and raise crops, animals, trees and build the farm of your dreams, you might soon be in the minority among your social networking friends.

The San Francisco-based Zynga says FarmVille is the largest and fastest growing social game of all time, boasting 11 million users nine weeks after its launch. To put that into perspective, that's roughly the same number of subscribers for Blizzard's insanely popular World of Warcraft game.

"FarmVille's growth is nothing short of spectacular and a clear indicator that we have a winning formula for giving players around the world a virtual farming experience that they truly enjoy," Mark Skaggs, VP and GM of Zynga's Social RTS studio, says. "By combining the best elements of social gaming, with people's instinct to nurture, we've created an incredibly fun, wholesome and rewarding experience."
