Is there any hope for Linux support?

I think if it's feasible at all, you should add them.

As noted, there are a lot of games on here that many people feel treat GOG customers as 'second class citizens' because the devs don't feel the need or desire to provide the same benefits/features/updates/fixes that the Steam user base gets. This looks pretty bad in the eyes of many GOG customers, since it appears that the devs are just dumping a game here to take the money and run and ignoring what can be a very loyal user base if treated right.

I personally don't care about achievements, but consider this another +1 for including them.

My opinion: don't include achievements! A useless waste of time. Most people here don't use GOG Galaxy anyway, there is just a vocal minority on the forums.

Oh, and please ask GOG to change the developer name from "inkle Ltd" to "Inkle Studios" so people can see you developed 80 Days too.

That's a good joke.

No worries. Personally, I understand that for a small dev, things need to be prioritized. There are others here that are... less forgiving about that though, so, yeah. If possible, I highly recommend adding them. Cheers.

In that case, let me give you some anec-data.

On these forums, we have plenty of Linux users who have hundreds of games (if not more than a thousand) in their GOG library. It seems like Linux support comes up in nearly every release thread for games that do not offer it at launch. I know many Linux users who simply do not buy new releases without Linux support at all. (It also comes up in Galaxy discussions all the time; GOG does not support Linux) While most of us do buy some Windows-only titles that run under Wine, we tend to wait for massive discounts and/or only buy very old games if they come without Linux support. Because we want to nudge and encourage developers to go in the right direction. Recently, I spent >800 EUR in a giveaway, and I did not consider any title without Linux support for inclusion.

I hope you get the idea.

Of course, I would also love to see feature parity with Steam. As a software developer, I find it quite bizarre how some game developers make it so difficult for themselves to maintain feature parity on two or more storefronts (while many others, ranging from solo indies to big studios have no issues delivering everything, everywhere, on time). But things like achievements don't even register when it comes to my personal purchase decision, and I know this is the case for many others on GOG since many of us don't use Galaxy at all (even though, yes, some titles do have built-in achievements that work without any gaming client; well done guys!).

You also mentioned key rebinding. That's a pet peeve of mine, since I use a split ergonomic keyboard with a custom Dvorak layout. Then again, I also know left handed people and people with disabilities who find it impossible to play most games that don't offer rebinding. I feel that omitting such a basic feature verges on neglectful. While I can figure out how to remap keys even in games that don't offer support for it, I just don't usually consider it worth my limited time to fight such things and thus, upon discovering that some game does not allow rebinding, it gets removed from my wishlist. I'm probably in the minority here, but thanks for hearing my anecdote. :)

If you lag too much behind Steam (for updates, achievements, whatever) you may also get negative reviews. Dont know if lots people care about it or if its just a 'vocal minority' but I have seen many complaints in the forums about this kind of thing.
Personally I dont care about achievements but if I know (by reading reviews or forum) that a developer doesnt update games properly in comparison to Steam I am very unlikely to buy a game and will - if I remember - put that developer on a 'mental black list'. (And arguments about priorities or whatever will not convince me otherwise - I see them as obfuscation or deflection. Only pointing your finger at GOG being responsible for delays may have 'clout'.)

Sorcery! doesn't have achievements on Steam.

I like achievements on GOG, they have satisfying audiovisuals. I try to interact with the Steam profile gamification as little as possible ("years of service"? come on.)

(Bought the game, obviously.)

Anyway, if we're doing this vote for most personally important feature thing, I vote fixing the javascript crashes in Inky for win x64. I'm ~this~ close to trying to build my own editor for PC with whitespace and hookers.

And this is an important thing to point out, since many developers / publishers in the past have used GOG as a garbage dump for games they never intended to support here properly. That kind of behavior is what prompted me to add a wishlist entry for a blacklist: https://www.gog.com/wishlist/site/blacklist_like_opposite_of_wishlist_for_games

I only heard about this game when it released here this week, tried the demo on Steam and bought it here straight after. It gives me a similar feeling that The Longest Journey gave me while I was playing it, awesome game, thanks for bringing it here GOG and devs.

Of course people care! From when galaxy launched, many people have switched over, especially newcomers who came from steam. On both here and GOG reddit, some of them are lamenting the absence of achievements on GOG, while there are on steam. Keep in mind that achievements are another another reason for which EGS is was/is hated too.

I repeat myself though: I'm not trying to attack you or anything, but asking if people here want a basic feature which should have been implemented from the start, it's a bit disrespectful, since it make us feels like we just eat whatever thing you throw at us.

I respect though yout willingness on adding them instad of outright not put them and ignore our requests like it happens on other games on here.
