GamePass PC stuff.
The PC GamePass list is up also and it looks damn good. - https://gg.deals/no/blog/full-list-of-xbox-game-pass-for-pc/
It's also listes as £1/$1 for the first month and the actual monthly cost is crazy good and cheaper than console GamePass at £3.99/$4.99.
I'd also say this is a great sign for the new Xbox PC store as a lot of the games are launching into it today with some pretty big games and publishers doing so and if the re-design is good then MS could have a decent offering for PC gamers and potential for some big subs/sales.
