This may be the year that some significant changes are made to Google’s Play Games service.
Google wants to eliminate permission requirements that are unnecessary and reduce the amount of times users have to sign into apps. To fix the issue, Google is thinking about moving the Games API’s to a new model. However, they’re skeptical because of the issues that could arise for developers. Hopefully this is nothing too major. Here are some of the changes taking place:
The most significant change users may realize is that Play Games will no longer require the need of a Google+ profile. The two services will no longer be connected, meaning that Play Games will provide you a name that is completely unrelated to the name on your Google+ profile. This has been complained about for quite some time and it’s great to see that Google has finally noticed it. Users may also notice that the amount of times they’re required to log-in is significantly lower. Users will only have to sign-in to the service once. Best of all, it will be done automatically when going into a new game for the first time, unless you have more than one Google account tied to your phone/tablet.
The changes will me made sometime in 2016.
