>> Valve did build out a lot of features like Remote Play and streaming on Steam, but just to a level of ok functionality.
I think Remote Play works brilliantly? I've finished multiple games using it, streaming from the PC at the other side of the house to the TV with SteamLink in the living room, using an Xbox One S controller. I hardly see a difference compared to sitting directly behind the PC (granted, this is limited to 1080p on the SteamLink hardware, but my eyes are old enough to not care about higher resolution anymore).
