I'm not going to get into a big back and forth about this, but This List would tend to disagree with you.

For this example, well, you fully support CD Projekt RED. While on Steam, Valve takes the 30%....Also Witcher on GOG is cheaper than on Steam.

Dude, what on earth are you talking about? Plenty of games bought on Steam don't have DRM. Plenty, as in really plenty.

Sorry, but you're completely wrong.

(and incidentally, .000000001% would amount to a tiny fraction of a single game. If only 1 game in a thousand had no DRM (the numbers are actually much bigger than that), that would still be .1% which is a hundred million times larger than the number you gave.) I think he meant football and not acting.

GOG has DRM-free installers (though there has been recent controversy about Galaxy being included with some of them). Depending on your internet, this is very beneficial for some people.

For instance, my family had really slow internet at home until 2013-ish. Thus client-free, DRM-free installers were beneficial to me - I could download them at work and play them at home.

This topic grinds some people's gears but it's an important one.

That's really not true. GOGers get regularly treated like second-class citizens by developers, often delivering patches for GOG versions much later and sometimes not at all. And usually developers don't seem to be active in GOG's subforums for their games while they are highly active on the Steam forums.

Many games in gog have no choice of achievements or game in the cloud. Many developers answer questions in the forums of steam but they do not answer questions in the gog forums.

However every day more games have in gog the same options as in steam, especially now that gog galaxy is the final version.

But yes, some developers are very bad at gog users.

You get the added fear of the day when day take away the offline installers here.

What fear? That's why you have them backed up and simply walk away if they would do this...

If you're fine with DRM, buy from Steam. You'll have better functionality with their client.
If you aren't fine with DRM (let's say you morally want to buy DRM-free or you worry that you may lose your internet connection for a significant period of time and not have access to your game), buy from GOG. You'll be able to do whatever you please with the installer after it's on your computer.

Does this mean that I can purchase a game on Steam and acquire it without installing their client at any point in time? If so, then that detail has changed since last time I looked. Because previously on Steam: no client = no access to your game download. I thought I heard whispers of some way around the client to get downloads, but does that mean I can experience Steam start to finish without their client, at least for the otherwise DRM-free titles?

Actually a serious question, because that might open up some purchase options for me.

If it is a serious question then: No. You need client for the download. After that, they're DRM free, meaning can play them without any internet connection ever.

It was serious. My first encounter with Steam required the client to play a game I bought brick-and-mortar, and that was a big WTF moment for me. But over the years I thought I remembered talk of a command line way to get at ones library, or something like that.

So I'll call those titles half-DRM-free. If the Steam client is considered DRM (I do, because it's an extra unnecessary layer with its own rules) and you need it to get at your library *of installers* (edit) - even for games that are DRM-free once you have the installers - then I can't quite bring myself to say they're completely free of DRM from Steam.

Because, when you purchase through GOG, you OWN a copy of the game to do with as you wish - only, without disc and associated physical paraphernalia.

When you spend money in Steam you purchase a digital licence, which then allows for continual access to a solitary instance as long as you remain online with Steam.

GOG = buy
Steam = rent

I'm slowly playing through my Steam games, transferring some titles I currently "rent" from Valve to my GOG wishlist, while only making future purchases through GOG.

I am not one of "The Many" [Cultural Marxism] and won't be committing my life to CERN's internet and its hive-mind feedback loop central global "management" ("Minority Report") AI - "biocuration"

Which is why I abandoned the horror of (the permanent online data-stream) Win10.
While I still use WinXP Pro x86 and x64, my gaming machine currently runs Win7 Ult x64 and will remain to do so until I am forced out (through continual data-harvesting demands or planned-obsolescence) and permanently onto Debian, Slax and openSUSE - and even Arch, if I still care enough about computing in the future.

Yeah, with remarks like "Game WILL NOT SAVE OR LOAD if run outside of Steam." :D

That's one important point for me: those listed Steam games are not officially supported as DRM (or client) free. Some have some "hiccups" like the one mentioned above, or e.g. Fallout 3 is "DRM-free" only by using a third-party tool, etc. etc.

I recall how the original "Steam DRM-free games" list here included e.g. Crusader Kings 2... but later it was found out that the DLCs still needed you to run the client. Also that list is full of such remarks that only some parts of the single-player game are DRM free, e.g. the expansion pack is but the base game isn't.

Barca of course.
And we have a consensus. Achievement unlocked.
