Microsoft has just released the official list of Xbox Series X optimized titles at launch. It turns out that there's going to be exactly 30 of them on November 10th, which is when Microsoft's high-end next-generation console will be made available globally (provided you've reserved a unit, of course).

Predictably, the list of Xbox Series X optimized titles includes several of the first-party games released recently by Microsoft Studios, with a few exceptions: Bleeding Edge, Crackdown 3, State of Decay 2, Minecraft and Minecraft Dungeons, Tell Me Why, and perhaps most puzzlingly, Halo: The Master Chief Collection. Of course, these could be added in the next few months.
