Other than Unreal (the game), there was hardly any big effort to support GNU/Linux from Epic side.
Exclusivity has no place on a decentralized market. When Sony and Microsoft do it, it’s still reprehensible, but understandable. This is inexcusable. People defending such deals (including Sony’s or Microsoft’s or Atari’s) are idiots.
I understand where these companies are coming from. I would too love to have more games available to me on OS X but the simple fact is there are not enough customers to spend money to develop directly for it or even contract out to a software house to write a wrapper. Let alone how many complain how much the games or DLC cost are worse on some platforms compared to others.
Now it is more profitable to get cross platform with PC and game consoles.
This is just my few pennies about that train of thought.
That could be to support Android or game consoles like the Switch.
I can only think of 2 possible reasons-- (1) the support costs are too high for the number of players (online competitive game, I'm sure there's quite a bit of dev time involved in securing the clients & preventing cheating that is Linux-specific) (2) Valve is supporting Linux, epic is busy feuding with valve, and this is similar to a petty toddler breaking their toy so they don't have to share.
Could be either, but I don't see how market penetration of windows in Asia could explain it
