Hmm, i realy wish to see on gog an old (1995 i think), but in my opinion, even now the best and most real merc simulation on PC: Earthsiege 2 published by Sierra
and Incubation: Battle Isle 4, a TB tactical game developed and published by Blue Byte back in 1997.

Here is my list XD

No expansions listed, and some of the games are allready here.

Some great suggestions throughout (haven't read through all of them), but let me just throw some stuff which I second or (if they haven't been suggested yet, which I doubt) suggest:

Games I don't own but would love to which is why I suggest them:

Dungeon Keeper (the first one)
American McGee's Alice
Starlancer
Curse of Monkey Island (Monkey Island 3)
Full Throttle
The Lost Vikings: Norse by Norsewest
The Legacy of Kain series in general

Unfortunately, most of these are either EA or Lucasarts, so acquiring them can be nigh impossible... it's our right to dream, nevertheless.

Games I DO own, but I really think they should be features here for other players to benefit from:

Deus Ex
Severance: Blade of Darkness
Rune
Kohan: Immortal Sovereigns
Kohan: Battles of Ahriman
Kohan 2: Kings of War (may be a little too recent to be a Good Old Game)
Freelancer
The Movies (again, it's 2004, so may not be old enough, but still a perfect game)

Bull frog games are a must!

also cryo interactive have some competant games and would help bulk up the adventure catagory.
inparticular the slightly flawed Faust (or seven gamesof the soul) is a favourate.

it has a great story if a little unclear at the start. great art fantastic voice acting and the best soundtrack any game has had ever. I mean better than rockbands greatest hits. the soundtrack is that good.

I'd be fine with these:
Anachronox
Age of Empires Gold
Battlefield Vietnam
Battlefield 2 Complete (with the 1.50 patch they've basically made it DRM free already, but for those who don't own the retail version I'm sure GOG would be a good place to get it from)
Captain Blood
Commander Blood (two strange and awesome Cryo space adventure games)
Codename: Eagle (DICE's precursor to the Battlefield series)
Close Combat
Close Combat 2: A Bridge Too Far
Descent 2: Vertigo
Deus Ex
Dune (Cryo's adventure/strategy game hybrid thing)
Dune II and/or Dune 2000
Emperor: Battle for Dune
Duke Nukum
Duke Nukem II
Dark Reign + Shadow Hand expansion
I.N.C.A.
INCA 2
KKND Extreme
KKND 2
MechWarrior 2 + Mercenaries
MechWarrior 3 Gold
MechWarrior 4 + Mercenaries
Motor Head (DICE's futuristic racing game)
Populous
Populous 2
Populous: The Beginning
Prince of Persia
Prince of Persia 2
SimCity 2000
SimCity 3000
Sim Isle
Syndicate + Expansion
Syndicate Wars
StarLancer
Wargasm
WarWind
Wing Commander: Kilrathi Saga (1-3)
Wing Commander IV
Wing Commander: Prophecy + DLC
Wing Commander: Privateer
Privateer 2
Wizardry 1-8
Elite: Frontier
Tomb Raider
Wasteland
Oh yes, Cryo's Commander Blood with that incredibly strange 90's rave soundtrack included as a bonus.

JUST WATCH THIS AND TELL ME IF YOU WOULDN'T LIKE TO HAVE IT: http://www.youtube.com/watch?v=TAoSr-bdaxE

I'd love to see chaos gate, really want to play this game again.

Homeworld and Homeworld 2 on here would make my day for about the next two years..

Wow, I first have to say that I think this site will become a problem for me. I loooove old strategy games. And I think I'll be happily whiddling away my bank account in five dollar increments for a long time to come.

Some I'd like to see include

The Tone Rebellion is a really odd and inventive game from the 90s which has completely gone off the radar. Never had the chance to play it and really want to.

Metal Fatigue was a cool game, basically the same mechanics as Earth 2150 but with a big emphasis on anime-style giant robots.

The Battlezone series, especially the second one. Probably the original FPS/RTS hybrid.

Battle Realms was a neat little strategy/RPG game, a lot like Warcraft 3 (which it predated) but in an asian setting.

The Dark Reign series, basically just another would-be Command & Conquer, but it had some style

The Dune games, Dune 2000 but also Emperor just because I never had the chance to play it, and it did have a damn good soundtrack

DARKLANDS!!!

I'd love to see Alone in the Dark 1-3 here.
