The big games are missing - and that's a problem I can think of a few edge-cases where this could be valuable, but most people I assume would just play the game on the PC, rather than also run it on a Mac remotely.
You need to own the PC you're streaming from. Steam Link, for those who don't know, allows you to stream PC games onto a Mac, but it has a major catch. While I've been thinking about the woes of gaming on the Mac for a while, it came back into the headlines now that Valve released Steam Link for macOS. And last, but not least, Apple is still trying to figure out the situation with its Apple TV, which was supposed to be buoyed by gaming.
Apple's gaming issues also threaten its relationship with the creative community, something the company has always prided itself on. The issues start with the still-frustrating and alarming lack of important games, which give PCs an instant leg up.
