Not counting remakes or remasters and console exclusives, if you have one. And frankly, I don't think they've lost any quality or detail. Whatever genre you like, you have good games to choose from this year.
I've heard your complaint more than once, and I think your problem is that you're either more demanding or you don't enjoy video games as much as you used to. I love retro games too, but I can admit that they weren't perfect and that many current games will become classics.
Hades and Ori are awesome games , tried out ghostrunner didnt like that one death stranding is imho one of the games of doom :D walking simulator where you have to watch 30min+ intro just to be able to start playing so bad game :P
