It doesn't help that they don't push the platform, it is simply not as good on a device like the deck, or a TV, and Tim Sweeney is so hostile to Linux making it stuck with the awful Windows UX.

Games get my money on Steam because Steam provides me with a great experience to play those games. It's far more than just a CDN, and all it takes is to try to use an EA game on the Deck to see how bad other platforms are.
