I think Mac gaming really went south with the release of OS X. I remember there being a kind of 3D gaming renaissance in the PPC era where we got most of what PC got, well anything I wanted to play anyhow.Gaming on Mac has been a topic since… the beginning of the Macintosh. It was good and fun in the 68k era, not dramatic in the PPC era and started to decline severely in the intel era. However you could always install windows and that solved the problem. Now with the M series it will definitely by dead. Gaming on Mac will stay casual and a niche for bobo.
Gamers need a machine that you can tweak and evolve and one that is tuned for that purpose financially. The Mac is the opposite of that. You can’t change the hard drive (games take a lot of space) and you can’t change the memory. BTO is way too expensive for high memory/storage. Finally the Mac platform is too unreliable for long term planning in the sense that you cannot anticipate the roadmap, you cannot know whether the technology you are developing for will be here for 1 year or 10 years. The investment is high and the roadmap unreliable.
Quake, Carmageddon, UT99, etc.
You are right though, 68K was the time of Mac gaming. My avatar is from the Macintosh version Sim Ant (Color).
I think storage is a real problem for gaming on the Mac. I just bought a base M2 Mini which SHOULD be the entry point to Mac gaming but its hobbled by a paltry 256GB drive. I mean if somehow Red Dead Redemption 2 got ported to the Mac, its base PC counterpart takes up 150GB. Better not have anything left on that drive.
Now I know what I'm getting into with my base M2 Mini as a secondary computer, but just to get it up to snuff would cost another $400. Meanwhile a 500GB 2.5 SATA SSD costs what, $40?
