The Linux market is very small compared to Windows, I think it would only be worth it financially if they (had a clue and) made the game portable from the beginning. No doubt they have used Direct X and windows-specific APIs out the wazoo, so it would be painful to port. Developers who are clueful with portability would start with Mac and Linux in mind, even developing the game on Linux in the first place, and would use Open GL and other high-quality portable libraries to create a highly portable game. I'm disappointed that Frontier did not attempt to create a portable game from the get-go, apart from its own direct benefits, portable code tends to be higher quality and better organized.
That said, coding for Linux is very very similar to coding for Mac. Mac OS and Linux are both more-or-less UNIX/POSIX operating systems, and both use Open GL for 3d graphics. So it would not be a huge effort to do a Linux port after having done a Mac port, especially if they bear that in mind while doing the Mac port.
The main benefit of doing an Elite for Linux port, for Frontier, would be gaining the goodwill and respect of the Linux users. We are not exactly spoiled for choice with AAA games, and we tend to be extremely grateful for good quality ports.
i'm pretty spoiled for choice. I have about 200 linux games in my steam account, and barely have time to play my favorites..
It's a mistake to compare the linux marketshare to the windows marketshare. This entire thread starts with "windows will get the lions share of the market", that's obvious and a given, sadly.
My point is, as is backed up by Anecdotal Evidence(tm), that I hope Frontier isn't too disappointed with the Mac port's uptake, because if they're discouraged from doing the Linux port, they'll never discover there are more Linux0rs wanting this game than Mac people.
Additionally, as has been said before too, for the money i'd have to spend on a mac that would play E: D, i could build or upgrade a much more beefier Linux PC. Why would i waste my money on Apple for this game?
Finally. It's not fair for me to bring up Steam, since it's a game distribution platform with many games and many types of gamers, of course their linux usage count will be low (but steady, it appears). What would be more representative is the people who want to play THIS game (or games like it (i.e. Star Citizen)) which want a Linux version. People who are interested in space flight sims are disporportionately different than regular gamers.
another wasted US$0.02.
cheers,
