Disclaimer: Gaming is not my, er, "thing".
However, I do visit gaming discussions on occasion as this, er, "computing realm" provides a good minilab for understanding the interaction of a, um, "amalgam genre of niche market users"...or, "bubbleverse inhabitants", a phrase applicable to any niche user group. And, for understanding the machinations at the feeding trough for bubbleverse dollars with the manufacturers (hardware and software).
Apple's success, in part, since its early days of providing for custom typography, has been to provide, at the system level, functionality and features that set itself beyond the status quo. Having maintained that part of their DNA over the years has allowed them to continually create and reinvent "platform level" functionality and innovation and differentiation for would-be devs. Their path into M(x) being their current waltz of previous dance moves learned, perfected and evolved. Apple's strategy has never been to, er, "own" any particular bubbleverse but, rather, be an alternate, and perhaps more-compelling, system-level solution for devs.
For the gamingverse, Apple does not need to (and I'd argue, doesn't want to) sidetrack it's focus, from what it does best, by trying to be a/the niche gaming marketplace leader. Apple's, um, "gig" is to provide a compelling and capable and inviting platform for devs who might find added platform-value in providing their own gaming bubbleverse user-base products that work on Apple's OSes and hardware. Chasing niche-market graphics cards and displays has never been Apple's, um, "thang", but providing alternate platform solutions that can meet those same bubbleverse users needs, um, "is". LOL
All of the above, IMHO.
