I don't know who's actually using these kinds of game streaming solutions, or what games they're playing with them. The PSN version of the idea is basically unusable for FPS games, and I have a good broadband connection. Even Steam, over the LAN, Steam introduces a noticeable-enough lag that I just don't bother. But things like Stadia make it seem like enough people are getting mileage out of these solutions to make it profitable to run, so I guess I'm not the target demo.
