None of these games you mention take any resources on hardware, though, they'll work on anything, which is why they can be easily modified to work on Mac. BG3, on the other hand, most certainly does take hardware resources. If it needs to look anything like you'd expect, there is a serious issue of making it work on the average Mac. And that's the thing. There's no point in making it available for the million-dollar UltrApple, if it only sells two copies. It needs to work and be reasonably received on the average one. Which is more or less the same price as the average pc, but with half the specs.
