Or is it just one of Phil's balls in my throat?
Yeah. For me the service is unmatched for a constant stream of AA and indie games. A lot of indies are launching at $40 now. The savings are substantial for me.
I posted in another topic, but a game like Lake, I wouldn't spend money otherwise, but since it was on Game Pass, I tried it and liked it so much I ended up getting the full 1000 G score on it.
GP really is a nice portal to discover a lot of solid AA games on top of a regular stream of AAA titles.
