Unlike Google Stadia, a game marketplace mixed in with a subscription service, GeForce Now is free and allows you to stream games that are already in your Steam, Epic Games, Uplay, or GOG library.

Game Sync, the new feature for Chromebooks, automatically syncs your game library so you don’t have to search for songs one by one.
To sync your Steam library with GeForce Now, visit play.geforcenow.com on your Chromebook and open your Settings. You should see an option called “Game Sync”. Use this option to log into your Steam account and link your library to GeForce Now.
GeForce Now remembers your Steam library but cannot see when you purchase a new game on Steam. For example, if you buy Destiny 2 on Steam, you’ll need to go through the Game Sync process again to unlock it on GeForce Now.
