Sometimes installers yes, at least years ago. Not sure how often nowadays, at some point they started increasingly selling Steam keys, but in the past you got both.

However:

- Their offline installers might be lagging even more behind than those of GOG. I guess they felt "you can play the Steam version if you want an up-to-date game", ie. there is/was less incentive to try to keep the offline version up to date.

- The naming and format of the offline installers was all over the place, as HB just provided whatever they got from the developers, who chose the installer format and the naming of the installer freely.

I guess that is not necessarily THAT important, but it just means different HB games install to different places, the naming of the game installers can be very obscure (I e.g. recall some game being called something like "setup_game_SB_22767632.exe"; good luck trying to remember what game that is, without running the installer), and some games didn't even have an installer, but just came with a zip file that you decompress yourself.

I guess those "zip-file" games are at least fully portable, with the games with proper installers, it may vary.

I'm surprised no one mentioned Humble Trove - if you are a Humble Choice subscriber you get monthly access to 80+ DRM-free titles that you can download and keep forever. There's games added/removed every month to keep up the variation.

Humble Bundle has been slowly killing Trove for a while now. In fact, in some of the past months this year, there wasn't even a single addition to the Trove, while the number of games removed has been bigger than the ones added.

i still remember when humble was teh place to go for drm-free
now i bare lee look at it. not worth

Not much I can add here as the people above have given all the information you need to your quesitions. The only thing I want to say is you can buy Chains of Satinav and Memoria there if you want to play them in German with DRM-Free.

As the above, it Humble used to offer a decent amount of DRM free content in their bundles (dunno about now since havent got one for years). Mainly a Steam key reseller.

There are still games that release finished.

Yes. Some developers still hold to the old paradigm of 'finished product'. (I'm looking at you Rimworld.)

But you have to look at the trend over time. Steam is a perfect example of what gaming could be if we let it.

All you have to do is support the devs that make the games the way you want and ignore the rest that don't. That's the beauty of computer gaming, everyone can do whatever the fuck they want to do. If they want to.

How do you support the devs of a game that is exclusive to Steam?

What do you mean by this exactly?

It may work the other way too, and DRM-free works for capitalism.

At least for myself I can say that I have already bough far more DRM-free games from e.g. GOG, than what I can hope to play the rest of my life (2119 GOG games, to date). So I have clearly bought much more many games than what I "should have".

At the same time, on Steam and other stores with DRM, I am much more careful on what I buy, and really try to restrict into buying only games that I am pretty sure I will play pretty soon.

So: I buy DRM-free games to an archive and I might not even play many of them, while on Steam and others I would postpone buying something until I am pretty sure I will play it pretty soon. The reasoning behind this is that I believe my DRM-free games to be more resistant to time, ie. I will be able to play them maybe even decades from now, when the store or service, from which I bought it, is no more.

Game hoarding in GOG is much more lucrative to me, than in DRM stores.

Me too. Partially because I'm afraid that all games will be online DRM in the future. I'm grabbing, and archiving the games I can before I can't get games any more (without online DRM).

Owning a finished game is an old concept. The next generation will not know what you mean by 'owning a game'.

We let this travesty happen, and we are culpable.

I couldn't agree more. Well said.
Plenty of people around the world are already looking at a client as a standard for managing their libraries, no matter the size. Handling offline installers, backups, folders and manual installation comes off as an excessive effort for some. Convenience takes precedence over everything else.
I had a chat the other day with someone, explaining them why I prefer DRM-free and backing up my games. They said it all sounds too difficult, when they can have everything handled by a client and various servers. When asked about the possibility of those servers shutting down and the business going belly up, their tune changed somewhat. "I guess I never thought about that..."
That in itself is a big problem, not asking questions and taking everything as it is.
These kind of tactics (employed by so many companies nowadays, including ones outside the gaming industry) will never be pro-consumer.
