Uh? You keep referring to a brand called "Silicon"?
To encapsulate A-series & M-series offerings from Apple. Per the ideas offered in this thread, the great abundance of A-series chips "in the wild" can motivate game developers to develop multitudes of AAA games... implying a relatively easy path to AAA games for M-series chips. It's a lovely bit of speculation but- IMO- it's not about the greatness of chips or even platform tech that moves development of the big games (see the Amiga story as perhaps the ultimate example), it's money.
The model that motivates AAA game development involves lucrative subsidies, buying gaming studios for exclusives and an end (consumer) market that is willing to pay more than phone app prices for the game AND accepting of in-app purchases AND accepting of advertising built into the game.
Apple doesn't seem to want to do the first two at all- just spin "we're serious about gaming" words and we Apple consumers seem to have little tolerance for PC-like game pricing and basically abhor in-app and advertising. As such, even if Apple rolls out an M20 in the next iteration of Macs with Raytracing super-retina mach 7 deluxe++ graphics, I still do NOT expect much beyond a trickle of AAA games for the platform. Why? Money talks much louder than words. Show developers a way to make MORE money coding AAA for Silicon and they will come. Else, we know how this movie plays out because we've seen it over and over and over again.
If some rich nut would allocate more money for AAA game development for Amiga or C64 than is available for PC/Console, there would soon be AAA games for those nearly-extinct platforms and ancient tech. Money will do it, not talk, not hope, not spectacular chips, no PPW, not our own love of the platform. We are collectively fooling ourselves (or each other)- AGAIN- if we believe otherwise.
If we Apple people want AAA games in abundance, take a portion of what we might spend on a good Mac and buy a PC with graphics card. Then you'll have access to a huge number of them
immediately... and many more in the pipeline. If we are embarrassed to own a PC, hide it behind the ASD and stream the video to our TVs via the Moonlight app for AppleTV. That's currently the way to play a wide variety of AAA games with at least some Apple hardware involved.
Else, hang in there and wait "a little longer" for all the AAA games to come to Mac. Maybe next year... AGAIN. If we can simply maintain the anticipation about "coming soon," it might eventually happen... someday.
