Google just announced a new gaming platform…yes, Google. It’s called Stadia, and the short version is that it’s a thin-client cloud-only gaming system. It allows you to play games from Google as a cloud-based provider from most mobile, TV, or PC platforms—even those that are way underpowered. This without a gaming console sitting next to your TV or having to buy other hardware (well, perhaps a controller).
Stadia works the way you think it would. The back-end cloud processing deals with the core game processing, data storage, and, most important, the rendering of the moving images transmitted to whatever platform you’re using at the time. You can start a game on your Mac, move to the 70-inch 4K in the living room, and then to your mobile phone on the train to work.
