Just a heads up, PC game pass won't be increasing in price and the games that are being removed are Exo One, Paw Patrol, and Spelunky 2. Xbox removes games from the game pass rotation quite often, wasn't too happy when they removed Katamari Damacy.
PC version is nice to play first party titles, but everything else is pretty hit or miss. A good use is getting an extended trial of several games and then buying them on a steam sale or something. It's not a very good deal unless you can play through at least one game every 2 months roughly.
With game pass we are still in the growth phase, so it's still gaining features (at least on PC) and the user experience is improving little by little...
