First, the company has confirmed that the Xbox Series X is formally launching in November, with support for thousands of games.
The number of games actually developed for Xbox Series X and launching with Xbox Game Pass Support is small, with only three exclusives listed: The Medium, Scorn, and Tetris Effect: Connected.
The reason Microsoft can make this kind of claim is due to backward-compatibility with previous generations of consoles.
According to Microsoft, there are more than 50 games developed across generational families launching before the end of the year.
