Having teased a new cloud gaming platform earlier this year, Google has finally got around to launching it properly.

Stadia offers games that are 100% hosted in the cloud, which means you don’t need a console, don’t need to install any software and can game on any screen with an adequate internet connection. Right now Google is only launching the premium tier, which offers 4K gaming but requires a £9 per month subscription and a 35 Mbps connection.

A freemium tier will follow in due course that won’t change a subscription fee but will offer reduced performance. It looks like both tiers will charge full-whack for individual games, although the premium one will chuck in a few freebies to sweeten the pot. Among the games announced by Google is a third version of the popular RPG Baldur’s Gate.

To seed the market Google is urging early adopters to by a Founder’s Edition bundle that includes a controller, a Chromecast Ultra dongle and three months subscription to the ‘Pro’ premium tier for £119. Here’s what you get for Pro versus the basic package.

The main telecoms angle here is bandwidth. Google reckons you still need a 20 Mbps connection even for 1080p gaming, which a lot of people, even in the UK, still struggle to reach. But the real strain on networks will come if people start using stadia via mobile devices. This is unlikely to really take off until you get games developed specifically for mobile, probably with a location and/or AR element to them, but when they do we might finally see a killer consumer app for 5G.
