Google presented Stadia, a streaming service for gamers

Google presented project Stadia, which allows players to start playing games instantly — just click on a YouTube video or a link and start playing at 1080p/60 FPS, stereo audio. The project supports any type of device running Google Chrome browser, including PC (most modern OSes), mobile devices and Chromecast. Though Google revealed it's own controller, users may take advantage of their own peripheral devices.

At the end of 2018, Google held testing of streaming service called Project Stream, letting players play Assassin's Creed: Odyssey - making it the first game supported by Stadia. Doom Eternal from ID Software will be one of the first games featured through Stadia. It will be available with 4k 60fps support. 

The technical specs comparison of Stadia:

Stadia will support multiplayer through a service called Stream Connect. It will facilitate features like asymmetric multiplayer and split-screen, where both players connect via a separate Stadia instance.

Stadia streaming

Stadia facilitates instant streaming of the gameplay to YouTube, meaning that players can play and interact with viewers without a powerful gaming rig. There is a "Crowd Game" feature, which allows a streamer to click a button and instantly invite viewers to his/her own game.

State Share

Players can instantly save the game state they are in, and share it through a link with anyone they want. It's similar to saving CPU state in various emulators. Players can play an episode of a game and challenge other people to speedrun it better. 

Release date

Stadia is launching this year in North America and most Europe at first. Google’s Phil Harrison promised to hold another presentation in Summer and share what games will be available through Stadia first.
