I’ve been using Amazon Luna to play Watchdogs 1. More specifically, the very fun Bad Blood DLC. I think this is probably the best use case for game streaming, where you want to play a game more capable than your dinky laptop can handle but you already pay for the service as an add on
The Stadia model of “buy full price game” doesn’t really work, but the Luna model of “hey, you already subscribe to Prime, here’s some games you can play” means that there’s no real worry if Luna disappears in ten months from now.
Anyway, now I have fast and reliable Internet, I can tell you that after playing for 2 h straight, I didn’t notice any artefacts or a single stream glitch.
