The PC gaming industry (AAA and such) seems more sensible the economy of money around the Apple Platform, for sure. But we're talking about iOS gaming... not exactly what keep the industry busy with complex technologies like RayTracing, cutting edge PBR textures and gigallion of cinematic rendered Quadruple-A art assets.

Epic Game Store is a special offender on two different side (outside the common BS from EA or Ubisoft). On the Unreal Engine side they claim full support, on their Store it's 0 (zero).

I wonder... are they actually making more money on MacOS rather Linux... or they are just "keeping their door open with Apple": stats are clear, you're more likely to see a Linux PC equipped with a RTX 4080Ti than any Mac. What kind of cutting edge gaming they are offering on their store for their exclusive Mac customers?

Only thing I can think of it's... just Fortnite. Fortinite is the only reason why they are sided on Mac side, even if market is lower. I think Epic would probably prefer to see Apple AAA gaming experience to fall in the void, rather promote Windows alternative to their customers (in which, in the end, would greatly help Apple-AAA if they embrace open software devices like Proton, Vulkan etc.).

In the end, I think Epic reflect perfectly the mindset of the AAA industry. Linux de facto boicotting (ie: Anticheat that disable linux support), it's not a real preference towards Apple.

...they just want to deal with Microsoft and/or Sony only (notice how Nintendo is mostly ignored too!). They see with fear adding factors to the top of the chain: Linux is an absolute no-no due it's democratic nature... which add deep uncertain to those accustomed with a single emperor/pharaoh figure.
