Today, Google began rolling out a small assortment of games, including the ubiquitous Angry Birds, EA2D's Dragon Age Legends, and sudoku. You know, Facebook stuff. A "Games" button at the top of your stream will take you to the available games, if the rollout has made it to your account. If it hasn't, Google says it will "soon."
Google's game implementation differs from Facebook in that game-related status updates are cordoned off into the "Games" page, so you can only see them when you are looking at game stuff. Unlike Facebook, you won't have to banish all your friends when they develop Zynga problems.
Update: Venturebeat reports that Google is only taking 5 percent commission on its games, another advantage over Facebook (who takes 30). And on the new Google Plus platform blog, engineering director David Glazer claims Plus is taking a "quality over quantity" approach with its games. Developers and new game features will be added in "small steps."
