I know, I know. 'Not again!' 'Gee, we haven't heard this before...' ad nauseaum
But maybe this is one of the first ones of 2020. Please stop reading here, if you are sick and tired of these posts ;) Also, Wall of Text warning!

TLDR - Ding dong, the king is dead, the king is dead! Long live the new king! Not gonna buy from Steam anymore. Gonna buy primarily from GOG. Because REASONS.

Background
I enjoyed Steam for the better part of 15 years. I had an account since Half-Life 2 released. In contrast, I have barely used GOG, or even Uplay, Origin, Epic, (apart from a few games) and...can't think of anything else atm. Steam was so dominant and convenient, I barely thought about its competitors, especially enough to purchase from them.

2020
That's all changed now in February 2020. My future purchases will be prioritised as follows:

1. GOG - buy first everything that is available for desired games
2. Everyone else except Steam (Origin, Uplay, Epic)

Now, many of you will not agree with point 2, I imagine. But as I abhor piracy and believe it destroys PC gaming, I really have no choice for some games than to buy from them. It's that simple.

Why GOG + others?
GOG will be my top priority, because of the following reasons:

1. Alternative to the behemoth of the industry - Steam
2. DRM-Free games result in less headaches for Linux gamers
3. Supporting the 'little guy''underdog''incumbent' competitor
4. Supporting a great (Polish) self-publishing studio

To expand on these, the 1st point regarding Steam being too dominant - I think this can be observed in many ways. Stagnant innovation and development, lack of new features periodically, relying on massive sales to sell games, being bad for the studios/devs/publishers because of their distribution cut, flood of non-curated low quality games, sitting on a pile of money whilst not contributing enough to gamers or the industry.

Don't get me wrong, Valve does contribute. Does it contribute enough to still warrant a massive distribution cut? Well, that's debatable. If you like a 'Facebook for geeks' like vidya gaming distribution platform, Steam is awesome for you. And I fully belong to the nerd/geek department, in case anyone had any doubts.

To be fair, Valve has also done quite a bit for Linux gamers - Proton is great, and really helps with running many games. And as Linux gamers constitute like what, 1% of Steam gamers (or maybe even overall), they didn't have to do that really. Of course they had ulterior motives, like not being beholden to Microsoft's mood and will, but still, the benefits for us gamers is there.

The second point is just simple. DRM usually causes some headaches when trying to WINE games through Uplay/Origin/Epic. THese days, there are some amazing tools/workarounds/scripting software, like Lutris to help that happen. With those, I'm playing Uplay, Origin and Epic games pretty much flawlessly actually, like Anno 1800, Borderlands 3, Phoenix Point, Dragon Age 3, etc. Multiplayer is usually a no-no, though. And at the end of the day, things can and will go wrong - removing the DRM part of the equation helps.

3rd Point regarding GOG as the underdog - this is actually more important than people believe. I mean, as an extreme example, if 100% of gamers only used Steam, it would be wholly detrimental to gamers/consumers - Steam would actually become the villain and start exhibiting monopolistic traits (much more than today).

Last 4th point - It is truly amazing what CDPR has accomplished, relying much on the success of its games obviously. And on top of starting out as a small indie studio, they are competing with a giant of the industry in digital distribution. Some would say, better even than Ubisoft or EA. Colour me impressed. By the way, the nationality has no bearing, but for one reason or another, I do have a connection to Poland personally, which is why I mentioned it. And no, it's not only because of vodka.

Conclusion and The End
If you got this far, please accept my apology for the length of my rambling soapboxing, possibly attention-seeking post. For some, maybe it was even entertaining, and/or provided a glimpse into how some users view GOG these days.

The END

Disclaimer: I should note, that I have been banned sometimes on STeam forums - almost always for derailing topics into politics and 'prone-to-huge-arguments' (I'm a news/politics whore). It may seem I'm disgruntled because of this and am doing all of this due to that, but actually, this couldn't be further from the truth. I had largely decided on this Steam 'boycott' before all that - the only thing keeping me over there, was some exclusive games I really wanted to buy and play. The latest ban was just the last straw. On the camel's back. Or hump. I forget the saying. No salt, I swear.

Another note and disclaimer - I have previously not believed DRM free games were good for the industry, and thus the gamer. I even wrote a piece many years ago, dedicated to that topic, even showed it here on the forums (like 8 years ago). I've been wrong before, and I was wrong about that too. Please forgive me (sob cry sob sniffle).

Terribly exciting stuff...

That's a new one. If anything there's been a ton of complaints here from linux users about the lack of support/games for linux despite them being available elsewhere.

Oh? You mean like GOG should offer more native ports, or something?

As for support, I personally don't believe it's the responsibility of the store to make sure games are running (especially non-natively) on OSes where they constitute really a minority of gamers. I mean, people dedicated to supporting and developing WINE or its iterations, still can't manage to support all games/ fix most of the bugs. How would GOG devs manage it?

Suggestion: Consider other sites that offer DRM-free games, like itch.io, before you include DRM-encumbered stores in your list.

Also, you say you want to support the "little guy", so why not support an even smaller and more niche company like itch.io? itch.io, unlike GOG, is not curated and as a result has many games you can't get on GOG. (The most well-known example of this is Celeste, which I own but haven't gotten around to playing, mainly because the game is a bit off-genre for me and I have other games which aren't off-genre.) Just be aware that political discussion is forbidden on this site unless it relates to video games.

(Then again, GOG did release an election simulator shortly before the 2016 US presidential election, which might not have been the best time to do that.) Actually, DRM does add one obstacle to Linux users; in order to play such a game on WINE without a crack, WINE has to be able to run the DRM the game uses in addition to being able to run the game itself. Some games actually do need a crack to run under WINE because the DRM does not work otherwise. A (partial?) list of DRM schemes that are (not) supported by WINE can be found at:
https://wiki.winehq.org/Copy_Protection

Welcome to Gog then! (even if your account is from 2012 lol)

I like this store for its DRM-free and its (usual) no-removal-after-purchase policy, BUT be aware about its problems, like: delayed updates of some new games, missing achievements or Steam-only features for many others, no Galaxy for Linux, etc..

You'll have to be patient and check some threads to get that info before purchase, like:
Games that treat GOG customers as second class citizens v2
List of broken GOG Achievements

i think this is more along the lines of what they meant:

https://www.gog.com/forum/general/gog_gives_middle_finger_to_this_linux_user_regarding_support/page1

Did you actually read that thread?
The OP demanded support for mods and Wine lol.

(wait.. you acknowledged that in a post.. I don't understand your point here exactly)

I meant that that thread was more along the lines of what this was referring to: imo that other thread is way too aggressive (the title alone is starting off on the wrong foot) and demands way more than a reasonable person would expect from support. and is also quite a contrast to the opinion of the OP from this thread

but /shrug, just my opinion

I don't get it. Why is everyone nowadays so hot on Poland, everyone likes them and wants to move to Poland? Just look at Hitler and Stalin, they both wanted part of it too.

;) That's true, though I doubt most recent people moving to Poland are bloodthirsty conquerors.

Poland's great though, if only to visit - nice hospitality, good cheap food, awesome beers and vodka, also quite cultural etc.

I'm also a bit biased as I have some relatives there.

Regarding CDPR - I guess part of it is pride - in Europe or Poland or whatever, though I try not to do that (I don't really like preferring one nation over another), but also the fact that Poland managed GOG and the Witcher series to become so succesful.

I'm just happy to see that Poland is known for, and in the news, for something other than the current um, stuff, that's a bit negative actually.

Oh crap. I almost did it again.

Sorry for the possible double post. Thanks for the welcome, mate. I didn't know that Galaxy didn't support Linux (sadface). I'll be sure to check those sites, as well. Ahh, I haven't really had any experience of itch.io, I need to check it out and read up on it. If it's as friendly as GOG, might include it in my list.

Celeste - I was for some reason listening to its soundtrack (really good btw) on my music streamer, then I saw I had it in my library on EGS (must have been free, I don't recall buying it).

Need to get through my backlog of games at some point...don't we all?

Love that a pair of this site's most persistent Scheme defenders were the first two to reply in this topic. Anyway, kudos to OP for doing something very rare: staying in the Scheme ecosystem a long time yet then getting out. It seems to me their business model is designed to get people spending more than they realize in sales, building up these huge libraries...thus making it difficult to then leave for a DRM-free store. The longer you stay in Scheme ecosystem investing more and more, the less you will feel comfortable about leaving. Sunk cost fallacy 101.

What's really devious is that Scheme didn't directly go for "100% of gamers" to become a monopoly. They just needed to aim for "100% of the big games" and it worked like a charm (to the detriment of consumers and gamers everywhere). Sure, there have always been sites here and there that sell games, developers selling off their own sites, etc...but if you want the big names of gaming, you HAD to go to Scheme or miss out on buying it, "...and you wouldn't want to miss out, would you?!?". Sadly, not much has changed except some publishers making their own proprietary clients (compounding the problem).

I am not familiar with the post OP references speaking out against DRM-free in the past, but again kudos for stepping out of what is a lot of baggage (not unlike a cult if you ask me).

I second dtgreene's suggestion of itch.io; most of the games on there aren't to my tastes but there are gems here and there.

It was definitely on the map before the Witcher 3. Studios like People Can Fly (Painkiller, Bulletstorm), Farm 51 (NecrovisioN), Flying Wild Hog (Hard Reset, Shadow Warrior), Techland (Call of Juarez). Yes, they were mostly FPS games, but good and popular ones nonetheless.

Saying that Poland got on the game dev map only after the Witcher 3 is just false.
