Gaming on desktop computers is still important. My two sons love playing games on our desktop computers. They both started with MacOS. They both were using MacOS on iMacs.
But a year ago, one of them asked to install Windows. I bought a copy of Windows and we installed it. Because of games. He has never since loaded MacOS again. His next computer will be a Windows PC. His favorite game just recently announced dropping support for the Mac. Now I can't play it (I love my MacBook Pro and my desktop setup with it, I have so far refused to dual boot Windows or get a second computer, a PC).
My other son also installed Windows on his iMac recently. But then wanted to switch to a laptop. We sold the iMac and bought an Alienware laptop. The MacBook Pro was completely and utterly wrong for this purpose. The 144hz display on the Alienware is amazing for games.
I don't think these two will ever go back to MacOS the way things are.
The state of gaming on the Mac is dismal right now. Here are some facts. Some are old news, some are new:
Apple may have been thinking they have so many iOS developers that can now make games for the Mac. But the gaming world does not revolve around iOS.
Apple doesn't seem to be doing "whatever it takes" to make MacOS great for game developers to support. Perhaps this is "niche", and they don't care so much. Perhaps they think the iPad is the future of computers. I doubt that. But something's wrong then.
It looks like, if I want to play "computer games" (not console, not iPhone), I will have to switch to using a Windows PC. My options are getting more limited every month, it seems.
