Sadly, this will be my last Games with Gold update. Xbox is shifting it's Xbox Live structure and Games with Gold will discontinue 01 September 2023.

That said, the new Xbox Game Pass Core will still provide Xbox Live internet and a selection of 25 games that will recieve new games 1-3 times a year.
