Xbox Game Pass has several day-one launch titles planned for the month, and Train Sim World 5 will be the third to join the list on September 17. Star Trucker kicked things off on September 3, and the remastered graphics and gameplay of an RTS classic followed shortly after with Age of Mythology: Retold. And when they launch on September 20 and 24, respectively, Frostpunk 2 and Ara: History Untold will round out the Xbox Game Pass Ultimate day-one additions, at least for now.
