They made an amazing graphics subsystem in Metal— it’s just very incompatible with everything else, so porting games to it is an outrageous pain in the ass.
It’s very possible to do amazing ports. I was blown away by the Alien Isolation port on iOS. There just has to be a market to justify the work. And if iOS ports can be recompiled for Macs (and they can) so much the better.
It won’t be ready for a bit for m4 but m3 and older can run asahi. Asahi now has support for steam so now you can run steam games on linux on Apple silicon with little to no setup. Works pretty well minus a 16gb ram requirement.
