I've been playing with a little self-hosted FOSS video-game streaming service: Sunshine.

Tested it via Moonlight on Android, and it works pretty well. You could give it a try if you're into this sort of thing, and you'd like to stream non-steam games to your phone, so you can play in bed or something. I don't really know how people use game streaming tbh.

You can also just use it as a remote desktop thing probably.
