Its less about "style" and more about economics and focus as you mention. For nearly the entire history of the macintosh, gaming was at best a second thought. (Snip)
Now streaming is becoming a thing, and that imo will further hurt the Mac platform for native gaming. Why spend the money to develop a game on macOS when those people (and others) can just simply use a streaming service to play.
The style question is forced by the hardware capability of the platform. The AAA titles developed for PC just won’t run so well on the Mac hardware, I doubt for example that we will ever see a Cyberpunk 2077 port for the M1. So if you look to Nintendo, they make money on hardware and software, they own nearly all of the biggest franchises on their platform, and they succeed in defining a family-friendly style of gaming for their market. Apple just get ports, and are non-existent as a destination for gaming.
Streaming is going to be an influence on the Mac I think. It neatly sidesteps the relative weakness of the GPU’s and there are plenty of capable browsers on the platform. I think it will prove to be a boon for Mac gaming, providing more choice for those people who do use their Macs for entertainment.
But it still won’t give a gamer a reason to buy a Mac. That can only be done by giving the platform a genuine set of exclusives to function as a draw. By ignoring gaming as long as it has, Apple has neglected a key function of the modern computer as an entertainment device.
