Just last week, Valve introduced a way to let you play games with friends who don’t have a Steam account, but the feature only let you play with one friend without a Steam account at a time.
Valve has also rolled out a big update to its Remote Play Together feature, which lets you stream games on your computer over the internet so you can play them with friends. The app is also available on Android, iOS, and Raspberry Pi. This new Linux version means that you can now stream games from a computer to a Linux-based set top box hooked up to a TV, for example. One change is the introduction of a Linux version of its Steam Link app, which lets you stream games from a computer to a device with the Steam Link app installed on the same local network. Valve is significantly expanding your ability to share games at home and with your friends for free using Steam.
