I usually go with Steam because it has all the other tertiary features that may or may not be there for GOG titles. I usually only use GOG if it's the only way to get a good old game or if that's the only version that will possibly work on a modern PC. I do not even consider them for brand new games, unless I want to pirate them to demo before buying.

In your case, you just so happened to choose right. Dark Corners of the Earth on Steam has hella issues and the game may not even run. But the GOG version is just fine. I also bought that a while back after watching a review of it and getting nostalgic (since I played it on Xbox back when it was new), and thankfully he had mentioned this or I might have been screwed.

Gog

I only use GoG if it's the only option. Otherwise I'll use almost any other service if I can.

GOG. I don't like steam so I try to avoid it where there's not a large price difference.

"rarbg.to" when it still existed.

I use Steam mainly because I haven't found any major issues with how Valve does things overall. It's been a fairly good experience for many years. Plus, with the steam deck it's much more convenient to have on Steam.

Now, I'm thinking if the price goes low enough, I'd pick it off GoG to download the installer and store someone just in case. I like the idea of having a backup just in case.

I actually use steam to install the GoG game installers and completely bypass the heroic launcher.

In short, I hope for the best, prepare for the worst.

Gog, drm free, just works, and devs get more money.

On the other hand, death to valve and steam. The launcher itself is dogshit bloatware and I do not have a single recent memory of it being remotely pleasant to use. The download and verification speeds are absolutely awful compared to Gog and, in my limited experience, Epic. valve was definitely a pioneer in microtransactions with tf2 and csgo. Locking mods to their storefront is fucking disgusting, as was their attempt to monetize them. There is also negative quality control when it comes to what's allowed to be sold on steam.

If it's not on Gog then I'll just pirate it.

What is GOG?

Assuming the price is exactly the same on both platforms (or even within like $10 if I'm not getting a Steam key from the GOG purchase), I'm buying from Steam every time. Mainly for the convenience of having it in my Steam library, so I can't just flat out forget that I own the game already when I finally get around to playing whatever it was, because god knows I don't immediately play straight through the vast majority of games I buy.

I use Steam. CDPR has burned me with several of their games and I refuse to give them money anymore.

GOG but I don’t because despite my 12 game library, I can’t gift because none of the games were over $15 and if I buy a game over that then it’s a 3 month waiting period

I like Steam’s Linux push but I don’t like their support and I don’t like their monopoly

I buy it on steam, because downloading the individual game installer files is annoying, and GOG Galaxy never worked right for me on windows.

On Linux, however, Lutris has good GOG integration, so I can just log into my GOG account via Lutris and install literally every game I own (which I have like 100 on gog) without much issue now.
