A Stadia Pro subscription will cost $9.99 Dollars / $11.99 CAD / £8.99, and includes streaming up to 4K and access to a growing catalogue of "older" games starting with Destiny 2 and expanding from there, but you'll need to purchase the latest games outright if you want to play them on day one.
Stadia will come with achievements for both new and old games, much like their console-based counter-parts and at the time of writing the UI is not ready for public display but is supposedly "looking good".
The first free title will be Bungie's Destiny 2, the popular multiplayer shooter. The larger offering (see: more expensive) comes with a ton of free games but those go away if you cancel. Pro allows for streaming up to 4K 60fps with 5.1 surround sound, but another crucial addition is free monthly games, which is what led to the Netflix comparison.
Game streaming sort of received its validation when Google, the most unlikely of proponents, jumped on the bandwagon and announced Stadia. To begin with, if you want to play on your TV, that will only be possible with a Chromecast Ultra and official Stadia controller together.
"To be clear, Stadia Pro is not "Netflix for Games" like some people have mentioned". But according to Doronichev, it won't come with any free games. Instead, it's an upgraded service based on an experience already provided at the free tier, comparing it instead to PlayStation Plus and Xbox Live Gold.
However, it will not be available by the time Stadia launches. He added that "nothing in life is certain, but we are working hard to make Stadia a success".
The other big takeaway from the AMA session is that Google is "super committed" to Stadia.
"We'll get all the basic functionality at launch - play games across screens, no waiting for downloads or patches, social, store, etc", he said.
"Eventually all of our games will be safely in the cloud too and we'll feel great about it", he said, adding that the company has been investing massively in "tech, infrastructure and partnerships" over the years.
