Valve may be working on its own cloud gaming service such as Google Stadia, Microsoft xCloud and PlayStation Now. This is evident from references to Steam Cloud Gaming on Valve’s partner website. Substantive details are not yet known.
Steam already contains several ways to stream games, but so far that has been functionality where users use their gaming PC to run the game. Steam Link allows users to stream a game to another PC, or to an Android or iOS device. In the past, Valve also made Link hardware, a box to stream games from a PC to a TV.
Google, Microsoft and Sony are focusing on streaming games where the hardware is not at the user’s home. Steam Cloud Gaming could be a similar subscription. Valve itself has not yet announced anything about such a service.
