I've done it (Steam "in-home" streaming, over OpenVPN to AWS). It's works fairly well. Latency wasn't an issue for playing Skyrim, but for competitive multiplayer FPSes it's probably a no-go. You can tune the bandwidth vs. quality in Steam.

I followed this guide: https://lg.io/2015/07/05/revised-and-much-faster-run-your-ow...

I found managing the VM on AWS to be a terrible pain. I may have misunderstood it, but it seems you can't just turn off a spot instance, have it persist and start it up again later. I had to snapshot the VM and make a new AMI after each run. You could possibly omit this if you don't want to persist the disk between runs.

Make sure not to accidentally leave your VM running or you'll wish you'd just bought a gaming rig; GPU instances are expensive, but it's fine for a few hours at a time.

As an alternative, I found: https://www.paperspace.com/gaming but I've not used it myself.
