What is how long do games stay on game pass?

As an AI language model, I do not have the exact information about how long games stay on game pass, as it may vary depending on the specific game and the terms of the game pass subscription. However, generally, Microsoft regularly adds and removes games from their Xbox Game Pass library, and subscribers can access and play the games as long as they remain in the library. Some games may stay on the game pass for several months or even years, while others may only be available for a few weeks or months. It's recommended to check the game pass library regularly to stay updated on the available games.
