There's no built in Steam-style DRM on GamersGate, and it's client-free as well. It's just like Direct 2 Drive and other such distribution platforms. Companies are free to use whatever DRM solution they want, as long as they allow unlimited downloads and activations (GG policy).
I've no idea why the site doesn't open for you, but there's something wrong there, then.

lol, you're wrong.

Can I download the game on my office PC and install it on my home PC which does not have an internet connection?
NO. An internet connection is needed to install the games.
If the target computer got a slow connection we recommend that you download and burn, or store in any other way, the downloads from a computer with high speed connection and move it to the computer with slow speed.
that's steam style DRM
Do you use SecuRom or any other protection on the games?
Yes, some games got some kind of protection. That is on request from developers and publishers. However, the activation limit that may be on this protection is easy reset by an email to support@gamersgate.com. ANY GAME BOUGHT ON GG IS YOURS TO DOWNLOAD AND INSTALL AS MANY TIMES YOU LIKE!
Hahahah.. GamersGate is fail.

You have interesting reading comprehension, Weclock - that FAQ says exactly what Zeewolf said it did. How does that make him 'wrong?'
And no, that's not Steam-style DRM. Have you ever used Steam? Or GamersGate for that matter?

it does use steam like DRM, having to be connected to the internet to install a single player game.. :D

Nah, I consider it to be a failure because there is no alternative to the DRM that is already built into the games, and still requiring online activation. Steam requires online activation, but is considered by many developers to be DRM enough, while with GamersGate it seems that you're limited to actually using whatever the developer provides, which in my opinion puts an emphasis on the developer to use additional drm.

Okay. Sorry, but that makes absolutely no sense to me. Sometimes companies use extra DRM on Steam, sometimes they do the same thing on GamersGate. They're free to do it on both systems. There's no difference there.
The differences between GG and Steam, DRM-wise, is that you can download games from GG with your web browser (you can also use their client if you wish) and that you don't have to run a Steam-like application when you want to run any of the games you've bought. You get more control over your own games.
I'm not saying GamersGate is better than Steam, but it's odd to me that you consider it a failure because its default DRM-system is less invasive than the one on Steam. But whatever.

Again, it's because their default DRM system appears to me, as if it's trying to get developers to use additional DRM, and that is not something that I approve of. Promoting the use of additional DRM is bad, sure DRM alone is bad, but encouraging developers to use more is worse.

What the Christ are you talking about?

It's a failure because it has shit games and no one has ever heard of it. Suck on that!

I said, it appears to me, as if GamersGate supports using additional DRM. As in they want people to use it.

That's absurd. Because GG doesn't use draconian DRM, this means they want companies to use draconian DRM?
Does not compute.
Especially considering they explicitly state they will make the worst DRM (activation limits) redundant by allowing users to download and install a game as many times as they like. How does that promote DRM?

I'm not saying that it's a fact, I'm just saying that's the way it appears to me. :D
Also, you know what I'd love to see on GOG? a game that interests me that I don't already have.

I was obsessed with Wing Commander (1) when I was a teenager. I remember running it on my old Tandy 1000 HX... barely... it would crash with out of memory errors after one or two missions. Good times... I remember just being floored with the then clever trick of using scaling/rotating sprites to simulate detailed spaceships. Of course nowadays it looks absolutely primitive. I loved every game in the primary timeline of the series (I was only slightly amused with Armada/Academy). The only WC I never got to play was WC4.
Origin used to make such awesome games, and I learned a lot about graphics programming just by watching the effects in their games and puzzling out how they worked.
I would certainly buy the series in a split second if it appeared on GOG, same with the Ultima series (yes, even including the awful U8 and U9 - just for continuity more than anything).
