My Gamepass subscription is about to expire, and I'm not sure if I'll renew it (Ultimate) - mostly because of the shit GwG offerings lately, and the fact that I've shifted most of my gaming to PC. I never play online multiplayer games, but that's free on Steam. Cloud streaming is cool, but I've only used it a handful of times, and if I needed it badly enough I think I would subscribe to Geforce Now and use that to stream the games I already own.
When something like Starfield finally releases, I might just get a month of PC Game Pass with rewards points and binge it. But honestly, I'll probably just outright buy it on Steam.
Sad to say, but for $15 a month I'd probably rather subscribe to Humble Choice ($12) and keep the games. Or buy a different $15 Humble Bundle every month that's got stuff I want. Game Pass is still a great value, it's just not for me anymore.
