I don't own such games from Steam, but I've heard persistent rumours that such old games like e.g. X-Com 1-2 and Doom 1-2 from Steam don't need the Steam client for anything, after the initial download. You can also run the said games from the executables directly, or so the legend says.

But I'm pretty sure they are merely exceptions to the rule, hence I was interested to know whether you are listing any sites that have any DRM-free games, even a few. I personally don't consider e.g. GamersGate or even Desura "DRM-free sites", because they don't make sure all their games are truly DRM-free and they allow DRM-games to be sold through their service.

Plus, I actually think that even for the "DRM-free" games on GamersGate, you have to do some special workaround to get past the GamersGate's inept DRM-system.

Isn't Desura DRM free?

Edit: After re-reading some posts I have found the answer myself. Damn, I'm lazy.

I think we need an actual definition of "DRM free".

Recently GamersGate don't use the launcher for the DRM free games so those are really DRM free.

As far as I know, any game on Steam that would use Dosbox should essentially be DRM free, so you can move them or you can RAR/ZIP up and set aside for later. (not that I have bothered personally, except with X-com, so I can't guarantee it)

Any Steam title that uses DOSBox is essentially DRM-free after it's installed. DOS games aren't compatible with the client, so once they've been downloaded you can move the game directory or back it up and you're fine. Those are the ONLY DRM-free titles from Steam, and the only reason is because it's almost impossible to implement.

GamersGate and DotEmu are your best bets.

No, there definitely are others -- for example Dungeons of Dredmor which doesn't actually require the Steam client to run (and this seems to be by design, actually). But these are all exceptions; it's safe to assume that a Steam game has Steamworks DRM unless proven otherwise.

Steam's Sega Genesis collection is also DRM-free. I've heard the same goes for Steam flash games but I've never tested it.

Maybe for new games? 'Cause Trine I got from you the other day still has the launcher.

So really at the moment for completely DRM free retailers we only have DotEmu and Gog atm?

Those two are all that I know, not that they are the only DRM-Free retailers in the world :-)

Do you know if there is a list anywhere of games like this?

I disagree with that. That file is obviously not meant for the customer to obtain, otherwise they would just have one download that as opposed to downloading an installer that required the internet and then having to copy an installer before it is deleted.
It would be like claiming that Steam is DRM free because one can go get some files and put those into the game folder to make it work without Steam.

Edit: Btw, I notcied an interesting looking first person perspective indie RPG on some site, but cannot remember what the game was called or the site. I know it was not Indievania, Desura, or GG. I know it is a long shot, but anyone have any idea?
And apparently GG has changed recently. May have to check it out, I got some free game I can test that with. Thank you for the info.

I did not say GamersGate is a DRM-Free retailers. Above I only said DotEmu. On those games labelled as DRM-Free on GamersGate, one needs to do that step I mentioned above to get the decrypted executable installer. Then and only then can that installer be considered DRM-Free since it no longer requires internet connection.

I actually have seen people complaint that the so-called DRM-Free games they get from GamersGate are not really DRM-Free due to the internet connection requirement while installing the game, and in general I do agree with them. However since I can get the decrypted copy of the installer (and I only own like only a couple of games on GamersGate anyway), I am still fine with that. True that GamersGate may not intend the customers to obtain the decrypted installer, hence why once again I only mentioned DotEmu in my original post above.

Not sure whether GamersGate changed recently or not. As I said I only have like a couple of games there anyway.

As for Steam, well, I do not like it, nor do I intend to have games there. Yes, I think Steam is DRM.

About the first-person perspective RPG, if it is not Legend of Grimrock, can it be either
Underworld (http://www.classicgamesremade.com/underworld-details) or Tomes of Mephistopheles (http://tom.kot-in-action.com) ?

Yeah, I think only for new games.

I don't think there is. I was looking for one a few times, but never found any.
