Facebook announced this week
its App and Game Groups beta, which allows developers to create Groups within their games or apps so Facebook friends -- and non-friends -- can connect around a specific app activity.
It's part of Facebook's efforts to help make social network games an actual social experience
"Game Groups help make games more social and engaging by creating another place where users can interact with each other. Group social dynamics help with retention and monetization," Facebook said in a document
explaining the concept.
