Google Play Games is giving up on Google +, as it will soon relinquish its Google+ account requirements to use. In order to get games and apps and use them, all you will need is a basic Google account. You will not be requested to give permissions and you will be signed in for all the games you have at once. This move should make your interaction with apps and games easier, especially if you don’t want your personal details to be linked to your games.
The transition to Google Play Games’ new policy should not interfere with users’ experience unless a game decides to use specific Google+ features extensively. For Google+ this means that it is finally reduced to a social network ( a barely successful one at that) and that its “catch-all internet service” days are over.
