I'd like to add my support for NOX, greatest game on earth =)

I was happy to play Stonekeep after so long, since I'd owned it but couldn't get it to run with XP.
Here's some more adventure-type games I'd like to see:
The Dungeon Master series (Dungeon Master, Dungeon Master 2)
The Eye Of The Beholder series
The Wizardy series
Elvira and Elvira 2
The Warlord series (esp Warlord 3)
Thanks to GOG for this great service. I know a lot of older games can be run with a little know-how and work, but I don't know much these days except I'm too busy to figure it all out! Every game I've bought from GOG has worked without any issues, which is saying a lot for some of these older games.

Xcom redone to work on Vista. Preferably using the patches from www.xcomufo.com to fix the sounds in the Collectors Edition.
How far back are we allowed to go with our wish list? When I first started playing computer games at home, they came on cassette tapes! :D

Kingpin
Old-School gangster game.

Realms of Arkania series.

"The devil inside"
Please :)

Carmen Sandiego games
Oregon Trail
Yukon trail
Rollercoaster Tycoon
Tetris

We most definitely need System Shock 1 & 2 up here. Those are wonderful games that all gamers today should be able to enjoy.

another old game that I found in my closet;
Battle Realms; I would guess it was an under-appriecated RTS when it was new.

World of Xeen PLEASE.
Me love you long time... VERY long time if you do this... *licks lips*

LAST EXPRESS.
It is on gametap, it is interplay's game, it is a good one and old one.
Perfect for here!

UFO 1
UFO 2 Terror From The Deep
UFO 3 X-COM Apocalypse
nuff said.....I never beat 3rd one, even tho I was at the end....I changed my rig and couldn't play the game anymore xD

Independence War series.
Especially the second one, Edge of Chaos.

The thread's way too long to read through, so my apologies for possible double.
However, my 2 cents would be:
- Deus Ex
- Deus Ex: Invisible Wars
