Starting from October 2022L’Xbox Games With Gold will no longer include games for Xbox 360. The announcement was made by Microsoft itself, which spoke of having reached the limit of adding new games for the old console to the subscription. Xbox One games, on the other hand, will not be touched and will remain part of the offer.
Any Xbox 360 title redeemed in the past can be re-downloaded, regardless of whether you are a subscriber or not.
Probably the move of Microsoft was born from the consideration that Xbox 360 is now a really old hardware and that, therefore, it no longer makes much sense to continue to offer games, even if they run on Xbox One and Xbox Series X and S.
After all, the Redmond house is increasingly weakening the Xbox Games With Gold in favor of its other services, such as the Xbox Game Pass, which are now its main focus. The reason should be clear enough.
