With the Valve Steam Deck officially out now (at least in some capacity) the company’s founder Gabe Newell sat down to discuss all things Steam. When asked by PCGamer whether Valve was working on its own competitor to Xbox’s Game Pass subscription service for Steam, Newell said: “I don’t think a [Game Pass equivalent is] something that we think we need to do ourselves, building a subscription service at this time. But for their customers it’s clearly a popular option, and we’d be more than happy to work with [Microsoft] to get that on Steam.”
 
Xbox Game Pass is an excellent service, however it is safe to say that Valve has the most robust tools and services on the PC gaming front, with Steam being by far the biggest PC client. Having to navigate Microsoft’s PC solutions in order to use Game Pass comes with its own issues – such as less mod support and controller connection problems. Using Valve’s platform to distribute Xbox Game Pass would certainly bolster subscription numbers. It will be interesting to see whether Microsoft takes Valve up on its offer – after all they will have to give up some revenue (in the form of storefront fees) in order to do so.
 
I hope Microsoft doesn't pass up on this opportunity. 

Microsoft and Valve can at least make an official Game Pass streaming app for the Deck. That way Microsoft won't be selling any games on their store or anything. Microsoft loves getting Game Pass on as many devices as it can. And Valve I bet would love to have brand new games running at Xbox Series X quality graphics on its new hardware (even if it is streaming vs native hardware). That's the beauty of Game Pass and why it actually might come officially to the Steam Deck in some form at some point.
 
I would love to get actual Game Pass games downloaded onto the deck and running on hardware.
