Are you saying “make games for non-Apple platforms” or “make games for Apple platforms beyond the Mac?”
Apple doesn’t have it in them to make games period. All their apps are designed for *other* people to make things, whether it’s presentations, videos, or music. Making games is simply not in Apple’s DNA. Making the *tools* to make games might be.
But say for the sake of argument they’re dying to burn cash and enter a highly competitive, high cost market. Making games for anything other than Apple devices would be anathema to them. They want to grow Apple’s customer set (providing incremental hardware sales and ongoing service revenue), not make a trivial amount of money developing a game for their competitor.
Even if Apple had a dedicated gaming console (effectively an AppleTV Ultra), they’d still focus on making it as easy for devs to bring their games to every Apple platform. Write once, run many and all that.
Personally, I’d much rather see Apple cozy up with Nintendo or Sony and see what type of opportunities there are for collaboration. Sony’s kinda/sorta trying to get back into mobile, but that could be a huge endeavor to do well. What if PlayStation games were available on Apple devices (either with a smaller App Store commission fee or as part of ongoing Apple Arcade Plus subscription)? Sony gains revenue and mindshare without cannibalizing hardware sales while also potentially slowing Nintendo’s dominance, Apple gains gaming cred and shows devs “real” games can run on Apple Silicon, and gamers get some of those AAA games they’ve been dying for.
That, to me, is far more interesting and likely to succeed than Apple buying somebody or starting their own studio.
