I surely appreciate this list. It's a pit of all the games I own on Steam (many because I got forced to use Steam to even run them, like Skyrim and LotR War in the North) only Divine Divinity made it to the DRM-free list.
I found out I had to run it in Steam once to update and configure, before I could run it straight from the Div.exe. Can anyone who tried this out tell me if all I needed do now is backup the complete folder? Will it run on a possible internet-less steam-less future computer if I just keep the folder?
I don't have DD on Steam so I can't test it out to confirm for you, but if when you run the game from the executable with Steam closed, the game does not force Steam to re-open before it launches, then it is in fact DRM free. If the game didn't run when you tried it the first time, but then did run after you allowed steam to do the first time install, that just means that the game needed some dependencies installed (for example, things like directx, visual studio stuff, XNA, etc.). These things can be installed without Steam. Typically with Steam games, there is a folder inside of the game folder called vcredist or redist or something along those lines, which contain dependency install files that are required for the game to function. These are often already installed from other game installations, but not always.
Also, some games on Steam can be patched DRM free. I don't mean using cracks, but rather if the retail patches for the game are DRM free, then you can usually download a retail patch for the game and either install the patch or, if the patch won't install for registry reasons, then you can extract the patch files with something like Universal Extractor and simply copy over the exe from the patch into the game directory.
