Will there be/can there be Mac & Linux versions ?

If linux version is released - i will buy this game in Steam also!

Did tried to search the community forum from PB, and nothing came up, looks like three people (including me) asked...

:/ ...

From what I have seen, the PB are using their own engine, DX11 based, so I think the chances for mac/linux port are not good, or more like non existent.

I disagree. I don't even understand the sentiment. Windows is by far the most backwards compatible OS for games you can buy. There is no technical advantage at all for using another OS (and the thought of people who have trouble with Windows trying to configure and run a Linux distro is downright laughable...;)), and Windows still commands in excess of 90% of the market--precisely because it is so backwards compatible. Windows support for hardware just clobbers what is supported by Apple or the Linux distro purveyors. I don't understand people who claim to like computer gaming but also won't use anything except Mac's OS X paltry OpenGL support (lame) or the slightly better OpenGL support *some* Linux distros support--because they automatically cut themselves out of a huge slice of the gaming market--so they can't like gaming "that much," eh? Windows is absolutely where the money is for game developers--as such Windows hardware support for GPUs and lots of other things is second to none. For people who don't game or for whom gaming is a take-it-or-leave-it proposition I can maybe understand the desire to use something else, maybe...;) Can't see any advantage to it, and many disadvantages, certainly. Some companies pay to have their Windows games ported to other OSes, so even then OS X and Linux users are not getting the original games at all, etc. Just can't see the fascination with so much self-deprivation...;)

I can mostly agree with what you wrote, but the problem is, that I don't have any windows at home, nor I'm planning to buy some (actually it's quite expensive last time I did check, and recently I think they don't even sell any reasonable kind of license, only half-sane way to get windows nowadays is OEM with new HW, or being corporate big enough to get your own pricing, neither will happen to me).

So I will rather pass on this one, for the moment. Maybe wine 3.0+ in a year/two/five will be capable of running DX11 and DX12 well enough, at the moment the DX9 games works mostly very well, and I have hundreds (800+) of games just here on GOG in library, can't even see when I will have time to play most of them.

It's just sort of sad that I would like to support my fav developers by buying their game when it is still fresh, then again my OS policy is stronger than the just fandom ... usually... (I still regret pre-ordering Witcher 3 from CD Project). This sums it up, I'm big fan of games, but the SW licenses and my control over what is my HW doing at my home is even more important to me. So it's a bit in conflict, and at the moment the best solution for ME is to ignore new games.
