Announcing this in a blog post at the time, the Forza team said: “On September 15, 2021, Forza Motorsport 7 will be delisted. This means that the game and its DLC will no longer be available to purchase in the Microsoft Store or available with Xbox Game Pass.
“However, after September 15, players who already own Forza Motorsport 7 will still be able to download and play the game and its associated content as normal. In addition, features like multiplayer and online services will still be accessible for those who own the game.
“For any Xbox Game Pass players who previously purchased DLC for the game, but not the game itself, we have good news! You will receive a token for the game through the Xbox Message Center so that you can continue playing Forza Motorsport 7. Token distribution will be through August 2. However, if after that date you have not received your token, please contact Xbox Support here. (Unused tokens will expire on September 15, 2023.)”
Explaining further why Forza Motorsport 7 was being delisted, the game’s official Twitter explained it was due to licensing agreements.
