Game Pass has been shown to increase sales of some games. Publishers can work out deals where the game is on for a month or whatever then pulled from the service allowing people who normally wouldn't buy it to play the game . When the game gets pulled some of them will then buy it. Also the publisher gets compensated for having the game on the service.A stock response to every 3rd party game now. Just say you not gonna buy it and force them into ignoring xbox next time
This game could come to Game Pass but it will likely be after it sells through to the market at large.
