It may not have been the best kept secret around, but Google's now made what's surely the biggest addition to Google+ in its short lifespan: games. Unlike a certain other social network, Google says games in Google+ are "there when you want them and gone when you don't," meaning that they won't flood your main stream if you never play them - you have to click the games icon at the top of the page to play and see updates from your circles.
