I think you did miss something. Netflix - pay monthly subscription fee - watch whatever movie you want in the library. No more to pay.Did I miss something? - cos ever since this was thought up, its been coined the Netflix of gaming. The subscription covers the cost of the games, just like on Netflix. They don't make you pay 1 fee and then another to watch something do they? Its a very easy sell for those that cannot save up funds, nor wan to dedicate funds to 1 device / console etc. Plus you can this cloud gaming anywhere on any device with a screen... Its the future and just has to be accepted.
Stadia - pay monthly subscription fee, you effectively have nothing. You still need to BUY the games to play them.
Unless I'm the one missing something but that's what I understand from everything I'm reading.
