I am implementing my own cloud save system, and I am curious if every user who downloads the game will have a play games account or not. My plan is to use the local google play games user tokenID [ ((PlayGamesLocalUser)Social.localUser).GetIdToken() ] as a mySQL primary key. Connecting to it files, and other data parameters. However, all this fails if a user does not have a play games account.
So I guess the basic form of the question is: Does every user who downloads a game from the google play store have a “Google Play Games” account?
May seem like an obvious one, but my entire system depends on it (and it isn’t clear if its a default for the user or not).
