Today we're adding games to Google+. With the Google+ project, we want to bring the nuance and richness of real-life sharing to the web. But sharing is about more than just conversations. The experiences we have together are just as important to our relationships. We want to make playing games online just as fun, and just as meaningful, as playing in real life.
That means giving you control over when you see games, how you play them and with whom you share your experiences. Games in Google+ are there when you want them and gone when you don't.
