You're padding that first list a bit with 3rd party:
XBOX SERIES X / XBOX ONE / WINDOWS PC
XBOX SERIES X / XBOX ONE
- Halo Infinite - 1st party
- Tell Me Why - published by Xbox
- Grounded - 1st party
- Psychonauts 2 - 1st party
- New Genesis Phantasy Star Online 2 - Sega, but looks like it's only happening due to Xbox's involvement.
- As Dusk Falls - published by Xbox
That's the extent of Xbox Games Studios cross-gen support. I think most people were expecting more than that after Phil talked up cross-gen support so much, but maybe that's enough to satisfy some people. Halo Infinite is the only big game that's cross-gen it looks like.
- CrossfireX - optimized for Series X, console launch exclusive
Thank you.
So now, even tho Booty and Phil was talking about XGS games, we can now include 3rd party....to say he didn't lie, its not confusing, lol.
Eventually one of these narratives will stick. Just gotta keep moving those goal posts.
