Google+ just added a games section to their interface.

Are there any ventures out there to integrate with that service?

(Sorry if this is a repeat. I couldn't find anything related to Google Plus in my search. Please PM me the thread if one exists)

Google+, now has games which integrate with the Google+ site, as well as the rest of google. Kind of how you can play chess.com games on facebook, as well as login with a facebook account to play here.

No, I don't think Google+ has opened up to developers yet. I signed up to be notified when that happens. I'd play plenty more chess if I could do so on Google+. The Chess.com Facebook app is shit.
