PlayStation Stars is a loyalty program that Sony is pushing for PlayStation gamers. PlayStation’s new program will enhance what you can do but won’t interfere with events like State of Play or community challenges. PlayStation Stars is exclusive to PlayStation products only. It comes out later this year and it will be free to sign up.
The loyalty challenges might consist of login once every day, play a pacific game, or enter tournaments to earn loyalty points.
Then u can cash those points in on your psn store wallet. So it basically like Microsoft rewards/bing rewards
