Am just interested to know what games if they got on GoG they would Instantly buy become of nostalgia or just wanted to always play it, or any other reason. Add the vote link if there is one so people can.. well, vote. :)

For me, Impossible Creatures is one of them, along with Rise Of Nations + , Age Of Empires[url= http://www.gog.com/wishlist/games/age_of_empires_1] 1 and 2.

I'm starting to feel like a broken record but the only instabuys I can think of nowadays is really old strategic, tactical, RPG or wargames from SSI or SSG.
Games like: The Gold Box RPGs, Dungeon Hack, Eye of the Beholder, Sword of Aragon, War of the Lance, Wargame Construction Set, Panzer Battles (All the games with the old Battlefront game engine.) and Warlords 1-3.
That's a quick list with most of the important ones.

Basically what I have wanted and hoped for since joining GOG. Really old games. I know that some of the old games from those companies gets into emulation for C64 and other old computers which is why I want that on GOG too. :)
I realise that the market for emulated and PC games from that era is very small and probably wouldn't make a profit. But I can dream. :)

Omikron - Played a demo once, and have always wanted to play the full game.

No One Lives Forever - Because it is my favorite game of all time. I'll instabuy as many copies as I can afford and give them out for free if it ever gets on GOG.

I would have said Shadow Warrior, but I've just checked and it has mysteriously ended up in my basket.

The Guild.

Blood Omen.

Also:
Albion.
Forgotten Realms Unlimited Adventures. (probably several copies of it, in order to gift them)
Dark Sun: Shattered Lands.
Dark Sun: Wake of the Ravager.
Grim Fandango.
American McGee's Alice.
Driftmoon.

Maybe not instabuys, but definitely going onto the higher priority wishlist:
Ravenloft: Strahds Possession.
Ravenloft 2: The Stone Prophet.
Menzoberranzan.
Dungeon Hack.
The Neverhood.
Discworld.
Knights of the Old Republic.
Bad Mojo.
System Shock 1 & 2.
Loom, Monkey Island 1-3, Day of the Tentacle, Indy 4, Sam & Max Hit The Road.

Too late for Bloodlines, I fear. Already got it from DotEmu when it was still available.

Omikron is an awesome game and i played it through several times. I absolutely had to buy it after i played the demo back in the day and i hope to see it here on gog one day because i'm not sure if the game still works on newer systems.

Don't make me say it...
