you fail to understand one thing... they are selling a drm single player games here on gog, they are also selling some gog galaxy exclusive games (even if multiplayer was not drm-free for some games even before, you didn't need any client).
Also the developer of Gremlins, Inc. will only release some update to the DRM version of the game so those who want to play with the drm-free version will use an old and not updated version.

I just cannot justify prefer gog anymore if they don't keep their own principles... I will just use humble bundle, developer site and sometimes steam (at least their client is not a limited browser like galaxy, and I can even add my not-steam games).

Sure I will still only buy drm-free game, but there are many drm-free games on steam too (and if I have to use a client there is no reason to use galaxy).

I would not call it fear, but will give an example why I am eyeing the developments here with Galaxy. If you read the comments in the new Bethesda release threads, you will notice many people calling for GOG connect and why it is not avaliable for them.

They complain, because they bought the games from a company which runs a closed third party system, meaning without the third party software the game will not be available or not be available after that company has closed down or not be available when they do not have an internet connection for a long time.

You see where I am going with this?.

PS

Before the "but some games can be run without" the client faction chimes in, I know, but that is not the point when only "some" games work or only work offline for a determined time.

Thanks for the link. If you cut through the fear mongering and stick with stated facts, it's a checkbox on install - not the installer itself. I have to go in to a separate page and make half-a-dozen clicks to change my folder on every install. Simply unchecking a box would be nirvana by comparison.

Having read all that, I agree that having a "No, never install Galaxy" option would be a good alternative, but wouldn't haters just start complaining that GoG is now writing arbitrarily into their registries? ;)

No they are not. they are selling ONE game on GOG were the single player is the EXACT same (minus online item drops) in two versions that you get in ONE purchase where one version needs online and the other does not. This is a UNIQUE case because they game was originally designed as an online game, not the norm. A completely fine compromise to most people here.

Any other case involving Galaxy deals with in development games covered by the user agreement you agree to when using GOG. Not released products.

That's not true at all, they said they would update the single player portion of Gremlins vs Automations when changes are made to the single player portion of Gremlins, Inc.

Which is your choice, doesn't make your narrative true however...

Sure because Steam provides installers, better support for old games, good customer support, and isn't riddled with 3rd party DRM that they don't always tell you about. Oh wait...

Steam some things better yes, but GOG very much still has a place and still does other stuff better too.

Never seen this game before. It appears that Galaxy is not needed for single player, only multi. The devs designed it to require a server, GoG/Steam have nothing to do with this. Would you prefer the game itself log into some online service that's just going to be shut off one day? I see what you're driving at, but you have to see past your own fears here. Having GoG in control of that server sounds far more secure to me.
Where did you find this information?

Pretty much all games on Galaxy can run offline forever with or without Galaxy for single player (except a few specific cases we already covered here GWENT (a in BETA game) and Gremlins, Inc. (for that use companion product that offers the same single player: Gremlins vs Automations) )

You can even transfer them from computer A to computer B without Galaxy if you know how to copy the registry (when it's needed). But it many cases you may find copying the game folder is enough.

It's different than on Steam, you will find on Steam launching a game will REQUIRE/OPEN Steam to play in many cases due to the Steamworks CEG DRM. This is not the case with Galaxy, games are not depended on Galaxy and running the exe will not open Galaxy at all.

But thankfully this is why GOG gives us standalone installers to make that process easy and convenient. I hope eventually they will also add a true backup feature to Galaxy allowing us to basically create our own standalone installers.
