Google is looking to build its own Facebook to defend against Facebook and its 500 million members running off with too many ads or even starting an ad network across other sites à la Google's AdSense according to the Wall Street Journal.

The search giant has reportedly been talking to online game companies about it like Electronic Arts, Playdom - just bought by Disney for $563.2 million - and Zynga - where Google is investing over a $100 million in aid of its plans according to the New York Times, which jumped on the Journal's story.

Social games are something people do a lot of on Facebook and it's a place for Google, which blew previous chances to get into games, to start. When it will trot out its rival is unclear. Supposedly it's called "Google Me."

The Journal says it'll build on Buzz, its social updating service. Google already owns the social networking site Orkut and it has an online payment system called Checkout that could be used to pay for social games.

The social games market was worth $700 million in the U.S. last year and is huge in the Orient.
