I have never really dabbled in GeForce now but I’m fairly certain it doesn’t allow you to link your own PlayStation or Nintendo accounts to their service. I’m talking about a
Movies Anywhere or
iTunes Match but for games. Navigating tons of stores or apps to find the particular thing you want is annoying.
If we are talking about impossible wishes for a streaming future, mine is one app to rule them all. Let me link all of my accounts to one app and play anything I own from anywhere with no discernible lag or image degradation on Wi-Fi or cellular. Also I don’t want to pay for data to stream these games in this future so whatever subscription I’m going to get bent over for better include unlimited network access.
