Please don’t make people play fall guys anymore. Epic has run that thing into the ground by laying off most of their creative team and basically deleting levels and over-monetizing cosmetics
The Guinness Reason is actually because Beyond Good & Evil 2 was teased in 2008 as a prequel to a game from 2003, while Star Citizen was known in 2012. Both haven’t released.
Actually, they kinda do take responsibility for mac gaming. They helped develop https://github.com/KhronosGroup/MoltenVK which basically runs Vulkan on Metal. The Linux version uses Vulkan, so in theory it shouldn't be too hard to port, they just didn't.
They still have some pretty old version of OpenGL and Metal was a bit before Vulkan, so it’s sort of a lightning vs USB C situation.
I don’t believe that it was easy. Since it started macOS was based on BSD, not Linux, which is quite different. They also use different types of binaries and the similarities between kernels should end beyond the BSD compatibility layer.
