I've been a GeForce Now subscriber since the start. It's a good service that is prevented by publishers from being great.

Two major pain points for me:

1) I can't play my whole library. During the beta I was able to play pretty much my whole steam library but that changed after GFN went live. I accept that some titles may have technical limitations but thats far from universal. Like, why can't I play Red Dead Redemption II on GFN but I can on Stadia? Pure publisher bullshit, that's why

2) I wish Nvidia made it possible to apply mods to games. Steam workshop mods work if supported but the majority of games do not support that. I don't often mod but when I do its usually to correct some 'quality of life' issue.

I ended up buying a Steamdeck to game on instead of GFN.. I hope the arbitrary restrictions holding it back disappear someday
