Over the weekend on the Android Developers Blog, Google announced a significant change is coming this year to Google Play Games. To this point, if you played a game on your Android device and signed into the service, it required you to have a Google+ ID to do so. It created a multi-step process for users and is a bit of a hold over from when Google tried to push everyone and everything through Google+. At some point this year, Google is going to eliminate this requirement and gamers will be able to sign in one time per account and any new games they start playing, they will be automatically signed into the service.
We’re taking steps to reduce sign-in friction and unnecessary permission requests for players by moving the Games APIs to a new model. The new interaction is:
Players are prompted to sign-in once per account, rather than once per game
Players no longer need their account upgraded to Google+ to use Play Games services
Once players have signed-in for the first time, they will no longer need to sign in to any future games; they will be automatically signed in
Note: Players can turn off auto-sign-in through the Play Games App’s settings
It is certainly going to make it much easier for players to sign into the service, especially on new games where they can just get to playing immediately without having to go through the whole sign in process repeatedly.
