I got roped into GamePass for PC some months ago with a trial to play Avowed - decided for 11 dollars or whatever it was I liked it enough to just keep it on billing for months. I used it intermittently and checked out interesting stuff I might not have otherwise - like 9kings - but beyond Avowed, I haven't put substantial time into any Gamepass game.
Sad to see it at 17 USD or whatever - not going to keep paying that, though. Not that I want any new features, I'd probably want less, but crazy they just hike by 40% and add nothing to PC.
