Steam has announced their own game streaming service today. The service is currently in prototype for Android, Raspberry Pi, and Steam Link devices. It will allow you to stream your games from any device as long as you have a strong internet connection rather than Steam Link which was only for home networks.
With Steam being the biggest distributor for PC gaming, it has a strong advantage against Epic, Discord and potentially Google’s streaming service. More announcements on the service will be announced at GDC next week.
