While I agree with you on the limited number of more capable gaming hardware Macs out there due to most ones are using the standard M chip (not Pro or Max) because of price, I think there's more to the situation than that.
I mean Switch 2 was just released and the sales seems to be in the millions already. How does the hardware of Switch 2 compare to the current M4 series of Apple devices? Seems the standard M4 is stronger than the hardware in the Switch 2. And a Mac mini with M4 is not much more expansive then a Switch 2.
So I definitely think it is not just about hardware here. Well, on the high-end gaming side there is. You of course get more gaming performance for your money going for PC/Windows hardware (not that the high-end graphics cards are especially affordable nowadays).
Apple also seem to give gaming attention when it comes to software with the updates to Metal 4 (
https://developer.apple.com/metal/whats-new) and Game Porting Toolkit 3 (
https://developer.apple.com/games/game-porting-toolkit).
So at least it seems there seems the foundations are there to at least be somewhat competitive in the gaming market?
Now, since there already are so many platforms out there where gaming is more mature I don't think it will be easy or it might not even work. Maybe it will help if Apple manages to increase the graphics performance in their M chips every year in a way that makes the platform more interesting for gaming compared to the other devices out there.
I don't know. We'll see what happens. At least I think Apple is showing more focus on gaming than I can remember they've done in a good while.
