I have nosed at game pass recently there are a few games on there I could quite happily play and may still pick up (not ultimate mind). That said you can see that there must be issues behind the scenes financially with everything they produce at the moment going up and up in price, I do think that with some of their recent acquisitions they must not have made anywhere near the amount of money they needed to, to justify the purchases.
That said if Sony keep their subscription as is I can see it really pushing Microsoft's Xbox side of things further down the crapper.
