SOMA on GOG?

Please, enlighten us of any DRM-Free games which are purchased through the Steam store.

Please note that, DRM on Steam applies to the fact that the games are tied to your account, requiring you to sign in in order to play the games unless playing offline. Also note that just because you can use another computer, log in, download and play does not mean the game is DRM-Free.

While it is true that you will need steam to at least download the game the first time, the Steam DRM on the games is optional and there are plenty of games that doesn't include it or make it so you can easily just remove a dll or two and continue playing the game, without steam.

I'm not kidding. You can try it with Amnesia: The Dark Descent. Download it, copy or move the files, shutdown steam and uninstall it, start the game.

Here's a list for you:

While I can agree that you need Steam the first time to download it. But that doesn't mean the game itself is not DRM free.
