AGREED!
Where is the myth series by bungie? Myth: The Fallen Lords, and Myth II: Soulblighter?

How about all the Monty Python PC games?
Complete Waste of Time
Holy Grail
Meaning of Life
Would love to get versions that work...none of these work on Windows 7!

All games made by Westwood and DreamForge Intertainment, in particular the Lands of Lore and Ravenloft series. I love most of Dungeons and Dragons games (http://en.wikipedia.org/wiki/List_of_Dungeons_&_Dragons_video_games). While the legal rights of many games I like may be an issue for some developers (Lucasart anyone?), I`m pretty sure that isn`t the case anymore for Good old Sierra Games. So please let us have more of these. (Craving for Quest for Glory the complete compilation 1 to 5 and some other great memories)

Albion
One of the best Dungeon/RPG ever, with scifi/fantasy setting, turnbased combat.
Yeah and Avatar is Albion ripoff :-D :-P

Prince of Persia 08 or 09 no drm should be easy enough to get.
zax alien hunter and NOX would also be great additions.

I Want That System SHOCK 2!!!!!
already 3 years of painfull waiting :<

Siege of Avalon
Nox
Anachronox
Baldur's Gate 2
Ultima 9
Grim Fandango
Dungeon Siege 1 and 2
Dark Colony
Darkstone
Crusader No Remorse and No Regret
Dark Sun Shattered Lands
Dungeon Keeper
Rise of Nations
Total Annihilation
Civilization 2
High Heat 2002 (I think that's the year...)
Great additions so far! I have been looking for these particular games for a while so it would be awesome if they could become a part of the collection.

Wizardry series
Maniac Mansion
Shadowgate
Uninvited
Zork 1,2 and 3
The Oregon Trail
Blood Omen: Legacy of Kain
The Witcher: Enhanced Edition
That's about all I can think of for now...

Albion
System Shock 1+2
Dungeon master
Eye of the beholder
All X-coms
That is all from me

I'll +++ Blade Runner. Great game.
There are two I'd love to see on GoG though:
-Black Dahlia, this has been mentioned several times
and it's Take 2 predecessor Ripper... which I think no one has mentioned yet. Despite its flaws, impressive game!
Ripper might be much easier to GoG, however, since it's a DOS game, whereas BD was a pure Windows (95...) release, and it's hell to make work well on modern systems.
But here's to hoping ;))

Baldur's Gate Series
Achimedean Dynasty

Z (from Bitmap brothers, difficult to find dos game)
Uprising: Join or Die (Does not work on Vista or higher)

SSI Gold Box
Maniac Mansion
Bards tale
old sierra games

I think Ice Pick Lodge games (Pathologic and The Void) would be a nice and realistic possibility. They are having a hard time funding their new game for this year and I think gog.com may help a lot. Both of their games are very new, though (2005 and 2008), maybe they wont sell The Void for $9.99, but it fits perfectly to Pathologic. And they are Russian, so you may get along well (Polish and Russians have always be good friends, right?).
It would be very sad if they have to close the studio. Even if I have a very hard time understanding their games, they are very creative.

Z! I had forgotten completely about that. I had used an Evergreen upgrade chip to make my 486SX/25 a DX4/100 in order to play that one!
