I wonder if this will grow to 4+ pages of people arguing. Maybe, maybe not!

Nah just four plus pages of eternal numptitude from all angles.

The first part of that statement isn't true, and second part of that statement is only true for some/certain games, but not all GOG games.

Also, I'm not sure who this thread's audience is supposed to be. All the people on the GOG forum are already well-aware of the reasons why they might or might not want to buy from GOG and/or Steam, so reading the OP isn't going to help them.

As for the OP's Windows 7 point, that's a moot point in the long run anyway, because what are you going to do when you have to buy new hardware and none of the new hardware on the market supports Windows 7 any more? Then your only choice will to be buy ancient & used junky obsolete hardware for the rest of your life, or otherwise upgrade your OS to a newer OS, the former of which is a horrible choice, and the latter of which renders your objections to Steam no longer supporting Windows 7 irrelevant.

As for point 2 in the OP, okay, I accept that as a valid reason for why GOG is better than Steam in that regard.

As for point 4 in the OP, I regard that as only a semi-valid point. Yes it's true that if Steam goes out of business, then you would not be able to download your games in a DRM-free format. However, the chances of Steam ever going out of business in actual reality are very close to zero.

And in addition to that, one also must consider that in some ways a Steam library is more secure than GOG a library (granted, point 2 in the OP contradicts that in other ways), because GOG's long-term future is always on very shaky ground, whereas Steam's is not.

And any possible method you use to back up your GOG games can fail, unless you are using multiple different Cloud services, which would be a giant waste of money every month, and also they might ban your Cloud storage accounts for storing other people's intellectual property (i.e. GOG games) on their servers, which probably isn't allowed, and/or unless you have multiple different physical storage devices that all have a full backup of your entire GOG library and also that are stored in many different physical locations (which would be a pain to manage).

In other words, OP's implications about how easy it is to conserve one's GOG library, and how this makes GOG so much better than Steam, is not nearly so easy & clear-cut of a matter as the OP makes it sound.

LOL.

Well exactly im not saying that DONT BUY on Steam, i been thinking pros and cons. In fact i owe lots of Denuvo games in Steam and huge library. but when GOG release a game that wasnt available to purchase in GOG i try to
buy to support the DRMFREE format. I hope soon Just Cause 3 and Just Cause 4 come soon on GOG.
You sure think but both are protected by DENUVO, not really in Microsoft Store Just Cause 4 dont have DENUVO, just Microsoft DRM. Denuvo takes around 20% of all the GPU/CPU.

Anyways guys lets hope we all support GOG and their owners CD Projeckt.

Thanks to everyone for comment.

For a very very very very very very very very old CPU this might be true.

The GPU however ... who came up with that idea? It doesn't even use the GPU, as far as I am aware.

As far as I know, GOG has better ports for some old games for modern hardware and OSes than Steam.

Manhunt is not offered on GOG, so there is no choice in the first place.
Last time I did run it on Windows 10 however.
Windows compatibility settings, dgVoodoo2 and indirectsound are your friend. For some that could be true (even if not many), since the GOG team personally worked on the titles, bringing them to modern computers. However, they had to accept some deals with the copyright owners(Attention, mostly hearsay).
The GOG team adapted the Star Wars titles (that's a fact), which then were also brought to Steam. So Steam is offering the GOG version basically.

No third party software needed, can have external installers that work offline. Games work offline (most of them). And that's it really, the only difference.

Assassins Creed Origins did exactly that in the past though. Two layers of virtualization (Denuvo + VMProtect + obfuscation (filling the CPU up with junk instructions to make reverse assembly hard to understand) as Ubisoft love to do obviously isn't 'free' unless someone has invented a 0 cycle CPU. Overpowered 600w desktop rigs regularly hide what becomes easily visible on a 25w laptop. In many cases Denuvo actually hits startup times more than frame-rates : "Game starts up about 40 secs faster without D sooo yeah Denuvo kills performance especially when you are using two Denuvos in one game" but since few people test for that, it remains ignored by most people who still claim Denuvo "has no impact" based solely on over simplistic frame-rate comparisons. No more of a 'pain' than what plenty of photographers, content creators, eg, do everyday with large non-gaming storage needs. I get that not everyone wants to backup their GOG collection, but those that don't often overblow the "hassle factor" and if you 'backup as you go' (copy the files to a backup drive after you've already downloaded them anyway to play) it becomes virtually an automatic 'no brainer' habit.

As for "do we really own GOG games or are they licensed", if you have them in your possession and can keep them backed up (potentially for life) it's as meaningless as arguing whether that 1982 CD that's been sitting on your shelf for 40 years is 'really' yours because somewhere on the back in size 2 font they may have used the word "license". If it works, will continue to do so and can't be taken away, the "you can't possibly own a book if you're not the author" argument that keeps doing the rounds on these forums is mostly artificial and not what people refer to in common language (keeping something they bought in their possession without owning the underlying IP).

No, no, no, no... hell no! Don't buy games with that malware!
By buying stuff like that you are giving companies a big thumbs up. We don't mind having malware installed, we will still buy your games!

Same as for CD and game, we need to distinguish between book and story. I own plenty of books, but no stories :P
