> My library of games on Steam, Epic, EA are obviously not accessible with Stadia
This is what convinced me to jump into streaming gaming with an NVidia Shield and GeForce Now.
You buy the games on standard game store platforms: Steam, Epic and Ubisoft. So I knew when I was buying the games that if GFN folded or I didn't like it anymore I could still play my entire library on a PC.
Not every game available on Steam is available to play through GFN. For example, you can't play GTAV. But you can play Destiny, Cyberpunk, Saint's Row, Assassin's Creed, etc. It's a credible if not complete selection.
The service was cheap (very cheap when I signed up with the Founder's lifetime rate at < $5/mo.) and I needed a new streaming device for my TV anyway (the Shield is a perfectly capable Android TV based streaming device), so I could dip my toe in it easily and see how it worked (basically the cost of the controller, which aren't very expensive). I've liked it so much I left console gaming behind and got two more Shields for two other TVs. It's very nice to be able to play the same game from different terminals, including my phone if need be (phone's not great for Cyberpunk 2077 but it does Powerwash Simulator just fine).
