Some hate it, many like myself love them: the cryo games. Having recently played Atlantis 1-3 which are very good and atmospheric (especially 1+2, not so much part 3), I crave for more! :-)

I'm sure the "value"/volume of the adventure portion of gog would greatly benefit from it. A few are available on the Microids site, but I'm sure they wouldn't mind another channel to sell their games and generate more income for them:-)
Below are my game suggestions (Please use the best source for graphics/sound possible, for some of the games there is a DVD-ROM version, gog :-) ).

No simplified versions please, like Purple Hills!

-Atlantis: Evolution
- The Secrets of Atlantis: The Sacred Legacy
-Lost Eden (wonderful, played it as a kid!)
-Aztec
-China
-Versailles 1685 (also known as Versailles: A Game of Intrigue)
-Versailles II - Testament of the King (not the crappy purple hills version!)

-Ring 2
-Salammbo: Battle for Carthage

Feel free to comment if you agree or if I missed some titles!

Totally agree, would love to see more Cryo games here. ;)

cryo's not just myst-like games, I'd also like to see all their other stuff.

btw Dragon Lore is already here

Dune, yes. Everything else, no. Well, I won't mind if they come here, I just won't buy them.

Cryo were a strange bunch. They employed (so it seemed anyway) some of the best graphics artists and sound engineers in the world, and some of the absolute worst game designers. Their games were generally extremely beautiful, very atmospheric and almost unplayable.

Except for Dune. That was fucking awesome.

Well, I guess it's not for everyone, love it or hate it :-)
I love these myst-like games, and Atlantis + Lost Eden were very playable for me and like was said have some of the best graphics (for their time) and atmosphere.
"Ring" however was practically unplayable (loading time between scenes, like 10-20fps). But I think this one was developed by Arxel Tribe. Maybe gog can improve the performance. :-)

But please add all the missing titles (also the not-myst-like games)

I played the first Atlantis game shortly after it was released. It was one of the most beautiful and atmospheric games I had ever seen, and the "puzzles" made me want to pull out my hair and beat the designers to death with a nail-studded club for failing to grasp the point of playing games at all.

Some of the puzzles I solved by tedious trial and error and some by sheer blind dumb luck. Few of them gave any indication of what you were supposed to do. Then I reached the orrery puzzle. After spending a lot of time on it I finally gave up and went looking for a walkthrough online. Wouldn't you know it, Cryo themselves had an official walkthrough on their home page! That alone should have been a warning. When a developer puts out a complete walkthrough for a game they only just released, that probably means they are aware that the puzzles suck. Anyway, I expected an official walkthrough from the developer to explain the logic behind each puzzle. Do you know how the solution for the orrery puzzle was described by the very people who designed it? "Pull the left handle 46 times, and the right handle 47 times". At that point I uninstalled the game in disgust.

Alot of them are Myst like though, and Dragon Lore 2 is still missing.
Find it to have some bugs with my original cds, maybe that is holding back GOG too, or the not so great sales of the first one.

If they are adventures and have anything to do with Microids count me in!! As you can tell from my avatar and name I am a point and click fan and have a special place in my heart for Syberia.

Count me in too. I would love to see more adventure games even the atmospheric games like myst.

My suggestion for non-adventure Cryo games:
- The Devil Inside (survival horror - reality show style)
- Gift (platformer game)

I wasn't even aware that KGB was made by Cryo. Yes, KGB is also a great game. I have fond memories of it.

Edit: I completed the list with the additional games that have been mentioned + many missing ones.
Speaking of Donald Sutherland. There also is a game by Cryo called "virus" (like the movie with Donald Sutherland, don't know if he's featured in the game).
I once read it is the worst game ever made... Did someone here play it?

I din't know Dragon lore was already on gog, thanks! Dragon lore 2 is still missing, then :-)

The only games by Cryo I played myself so far are: Atlantis 1-3, Egypt 1, China, Lost Eden, Ring, Versailles 1.
Looking forward to the rest!

this.
