PC games are ready to meet iOS, now that Valve's Steam Link app is available for Apple devices. You can easily play them on your TV via Apple TV, directly from your computer. Apple had blocked its release last year, but apparently it's been drafted – probably because you can no longer buy games with it – and you can take it from the App Store now.
Valve has also renamed "In-Home Streaming" which is simply Remote Play in the latest beta steam release, so it's the same if you use it at home or beta testing it further away. As long as the connection is good enough, it will work. When Steam Link started you needed another computer or dedicated hardware, but apps for iOS, Android and even Raspberry Pi make it much more accessible. It's not really cloud-powered games, but everyone with a Steam account full of games, a decent connection and one of those devices suddenly has a lot more options for how to play.
