If this scales to more titles I'm curious how it's intended to work. The article writes that the current internal test has preroll ads before the game streaming begins.
So, if I start playing a game and the system decides it's time for me to watch more ads, how does it handle the game I am playing? Does the game pause? What about in the middle of an intense fight? What if it's during an unpause-able section? What if it's a multiplayer game?
With these questions in mind I have a hard time understanding how this will end up working in the long run without completely ruining the experience.
