Do you keep Game Pass games forever?
The games are only playable as long as you have the subscription. Once the subscription ends, then so does the access to the games. If you want to own them, you have to purchase them.
Can you keep games after they leave Game Pass?
Can I still play games after they leave Game Pass? Games you install using Xbox Game Pass remain playable once they've left the Game Pass catalog only when you buy them—and you get a hefty discount when you buy games as an Xbox Game Pass subscriber. When you buy games at a discount, those games are yours to keep.
Will I lose my games if I cancel Game Pass?
The only thing that will happen is that the game will tell you you need to buy it or renew game pass. All of your save data, and all of your installations remain in place until you delete them.
Do games disappear from Game Pass?
Games may exit the catalog after a period of time. Once a game leaves the Xbox Game Pass catalog, you'll need to purchase a digital copy from the Xbox app for Windows or the Microsoft Store, play from a disc, or obtain another form of entitlement to continue playing the game.
