Amazon Luna is starting to be more of a hybrid of GamePass and Geforce Now. You can either subscribe to Luna or if you are a Prime member and have a Ubisoft account you can link your Prime and Ubisoft accounts and play some of your purchased Ubisoft games through Luna. I'm hoping that Amazon look at opening that up to Epic Games Store as well, since I have a ton of games on EGS that I would like to try.
On the subject of Cloud Gaming I keep seeing people on the web saying that if Microsoft drop out of making consoles, that Sony would have a monopoly and the raise console prices to $800 and games to $80 or $100 a game. Well I'm sure that MS is banking on that happening since they can then start pushing Xcloud as an alternative for parents unwilling to part with over $1000 to buy a kid a console. People are already struggling to buy $500 consoles and $70 games, Sony would be foolish to try that and I imagine that would hasten the end of home consoles much more quickly.
