According to PC Gamer, the announcement says “All local multiplayer, local co-op and split-screen games will be automatically included in the Remote Play Together beta”. A Valve employee, Alden Kroll replied a tweet where he also mentioned that the feature is only for shared-screen or split-screen games. Indicating that there is a selection of games by Valve that will support Remote Play Together. Interestingly enough, it was also mentioned that only one person needs to own the title in question in order to begin playing together.
This is not the first time Steam tried to let player share games. Prior to Remote Play Together, Steam had the Family Sharing feature implemented a few years ago, but it only allows games to be played by a single user at a time. Also, it’s unclear if Remote Play Together will actually work with every local multiplayer game on Steam, as some developers current do not allow their games to be shared via Family Sharing. At current, Remote Play Together will be entering beta soon, as Valve is eyeing a 21 October launch. As usual, the update will arrive on the Steam beta first before Valve decides to officially put them on the stable release. The Remote Play Together is expected to be launched on 21 October on the beta update. (Source: Alden Kroll via PC Gamer, Engadget, Polygon // Images: Rocket League, Duck Game)
