In case there are some nVidia Shield users out there who are not yet aware; nVidia is working on upgrading their servers. Till they get done with that (and it could take a while), the monthly subscription fee for Geforce Now gaming is on hold and shield users can play all geforce now included games and the ones previously purchased for free till then.
Some decent game titles in there (Tomb Raider, Hitman Absolution, Bioshock Remastered, Borderlands, Just Cause 2, etc) and even though my network test said that conditions were not ideal to play, I was able to play with no issues at all. I'm really surprised cloud gaming can work so well!
