Two curious things, the suggestion that devs pay to be on gamepass (seem this throw in one thread) or that they offer to put it for free on GP to get publicity (done here), last I heard publishers liked to receive for people to play their games not to pay for MS to profit from it.
Another curiosity is Gamepass have like 100 games on it? In 6 years of PS+ I have received at least more than 100 games permanently (considering my library says I have over 350 digital games and certainly didn`t buy more than 50, that is actually 300 tiles received some way or another without paying for it specifically). So PS+ and PSNow already do most of what GP offers.
