I already sort of do this with my gaming machine. It lives on a cloud host and I connect with a client.

It’s cheaper and more convenient than buying a new PC - especially since I’ve got three gamers in my house - and offloading graphics means I can get better battery life when playing on my laptop in my hammock.

However, if you’re more than a couple hundred miles from the data center or there’s network problems you won’t be having much fun. That’s the only reason I’d want an actual gaming machine, and even then I’d play via remote desktop from my hammock.
