Microsoft has announced the next batch of Game Pass titles, and this month should have something for everyone. On September 19, Jump Force and Bloodstained: Ritual of the Night will join the service. On September 26, you'll get Bad North, Dirt Rally 2.0, and LEGO Worlds.
You're in luck! We've reviewed for most of these games, all linked above. Out of all of them I'd most heavily recommend Bloodstained. Given the issues at launch on Switch and the weird cadence of patches it makes sense that a lot of folks would have skipped out on it, but the Xbox One edition was just recently patched to be up to date with the other editions (and fix the HDR issue), so this is good timing.
Jump Force might actually be one of the best "Game Pass games" in a while though. Billed as an all-star anime adventure it was riddled with issues, and some of them have been smoothed over with the added bonus of free content drops.
