Game pass, to my pleasant surprise offers tons of PC games to download, on top of that you can cloud stream directly to your browser or to your Android device. The quality here is absurdly high. I think Microsoft is essentially testing this cloud technology on video games, before they tackle the Enterprise. Uptime requirements for a video game are absurdly low, no one's losing money if they can't play Halo for couple of days.
There are a handful of games which are console only , mostly older titles but it hasn't bothered me all that much.
