I am currently in the process of implementing the Game Services potion in my game, which includes Device Login and later on Account links with either social media or just an email.
Now I was wondering If I can have a PlayFab ID, which works with the later games my studio publishes and thus creating a cross-over profile for the player for games published by my studio.
But then I think that instead of just present in the games from one company why not make PlayFab ID like Steam or PSN?
One PlayFab ID to rule them all, bring them all under one umbrella, reward them for completing diffrent games and maybe pool all their virutalgoods togther for trade?
