The Windows version available here does not work in wine with ease as it needs a special mono not included by default. However, there is a Linux version.

Hope gog.com makes Linux version available to those who bought the Windows version.
I'm not in a mood to spend time trying mono. Oh well, the sale price was worth the risk.

Why does not GoG offer a Linux version of some games although they are available for a long time. I would love to buy Dust but I only buy games that will support all systems.

As usual, it is not fault of gog. It is fault of too many people using Windows

No, it's the fault of too few Linux users bugging the devel/publisher for a GOG release.

I'm just gonna have to get it from the humble store then, cause dust is the only game I got on steam for linux that I thought I couldn't get elsewhere, once I have that and guacamelee:gold on gog, I could be steam free. I really hate valve

Not enough if you bought from them...

I think it's the fault of devel/publisher and GoG not coming up with a good agreement for a Linux release. The problem is not that Linux version is not available. it already is, but not provided at GoG. That has nothing to do with Windows users, since they don't care about Linux version (and Linux users wouldn't care about Windows version either if it weren't the only way to run the game in Linux.)

With the latest wine, most of the Windows games I bought from GoG runs perfectly under Linux, and Dust is one of the remaining three that still refuse to run in wine. And then there are three others that have graphic/video issue that renders them unplayable. I've decided not to buy any more games until these are remedied.

It does, fewer Windows users would bring more attention to gnu/linux by publishers and programmers.
Wine is just another reason that makes the excess number of Windows users unfathomable.

Dust Linux native version has been in existence for over a year, that is why Windows users have nothing to do with it. Adding or subtracting a Windows user will not change the past. Dust native Linux already exists.

GoG already provides Linux versions of other games, so the only issue is why GoG does not provide something that already exists.

Besides, most new Windows don't run many old games without tweaking or running in a Virtual Machine like Windows XP mode, so that is no different from Linux wine (actually, running in a Virtual Machine like XP mode would be worse than running on top of native libraries like wine, which explains why wine runs old Windows games better than running them in new Windows in terms of performance.)

Really wanted to buy this from GoG, but ended up buying the Steam version because it had a native Linux version. Please, please, please bring the native Linux version to GoG. I honestly might still buy it from GoG if it went on sale for cheap (and maybe if it included the full soundtrack instead of just samples).

I really like GoG and would almost always rather buy from them than Steam. But it kills me when Steam has better Linux support. :-(

Just wanted to mention that I did actually get this working on Wine for myself. I just did a native dotnet30 install using winetricks. It always gives a config parse error (which I just acknowledge/ignore) on startup, and often/randomly crashes after the logo/splash screen, but once it gets past that it seems to work fine. It's not my kind of game, though, so it's not worth putting any more effort into it. I might come back to it if gog ever gets a Linux native version, though, since I'm a sucker for pretty graphics.

BTW, congrats osce on only having 3/5 with issues. I currently have 8 completely unplayable games, 4 with serious issues, a few with graphic glitches, and 8 with unusable mod editors. I also feel that many of the Linux-native games are inferior to their Windows versions. It's annoying, but not enough for me to dual boot or buy an extra machine to use as a "wintendo" for playing those games.

Well, finally, after two years, we have Linux version of Dust: An Elysian Tail in GoG. I'm so happy that I can play this now. It was so worth it.
