Just a couple months after migrating launching a standalone site for mega-hit FarmVille, social game developer Zynga has further expanded the popular farming sim beyond Facebook to Microsoft's MSN Games portal.

As with the FarmVille.com version of the casual title, the MSN Games edition uses Facebook Connect so that players can still interact with the 76+ million FarmVille players on the social network. The version on the portal will still pull from users' information from Facebook even though it's no longer hosted on a separate site.

Though Zynga plans to bring more of its Facebook titles to MSN Games and Windows Live Messenger later this year, the San Francisco-headquartered developer did not specify which games it has in mind. The studio's popular social games include Cafe World (30.2 million users on Facebook), FishVille (25.3 million), Texas HoldEm Poker (25.3 million), and Mafia Wars (24.7 million).

"Social gaming has gone mainstream," says Zynga's Games SVP Mike Verdu. "People love to connect with their friends through our games, which are broadly accessible and have universal themes. Bringing FarmVille to a major site like MSN Games is a great way to expand the reach of social games and is a logical next step in how we deliver them to consumers."

“As hundreds of millions of customers continue to enjoy social gaming, we’re excited to partner with Zynga to add FarmVille to our broad portfolio of games on MSN Games," adds Microsoft's Windows Gaming general manager Mike Ybarra, according to a report from Social Times.
