Specifically 3D Realms' Shadow Warrior and Monolith's Blood?
Did Shadow Warrior and Blood ever see a special edition, actually, or were their expansion packs only ever independently sold?

I don't recall any expansion packs for shadow warrior. "who wanta some wang!" haha. I think Shadow warrior came out then died off quick. Never reached the popularity like duke nukem did.

Wikipedia has an entry about the three Shadow Warrior addons. Both Twin Dragon and Wanton Destruction are free to download.

They kinda suck iirc, don't they?

SunStorm (who made Wanton Destruction) made the Cryptic Passage for Blood and both Duke Caribbean: Life's a Beach and Duke It Out In D.C. for Duke Nukem 3D, which are considered one of the best unofficial addons for any games out there. I haven't played Twin Dragon, but Wanton Destruction is pretty solid.

I'd pick Blood up in a heartbeat. The "I live .... again" plus the sound of your coffin lid sliding at the start, the cackling maniacal monks all over the place, throwing dynamite at zombies, lots of secrets to discover, including "super secrets", great weapons, gory but not too gory, cool game from A to Z. Add Plasma Pak and Cryptic Passage to the mix and it's even worth $9.99 for me.
I never tried Shadow Warrior but I hear it's OK and I've kind of ... got a thing for old-school FPS games, so I'd probably buy that at some point as well.
Bring them on!

shadow warrior is fun. some of the weapons are great lol. i believe there is a cheat to shoot rabits out of your rocket launder too!

There is.

Nothing like blowing a bad guy across the room with a fuzzy little animal >:)

Yes please! Shadow warrior is my favorite build engine game and even though i really enjoyed Blood, i never really got to play it as much as i would like.
If any of those 2 games show up in GoG i'll buy them in an instant.

In any case, I'm simply wondering about the likelihood of this happening. I'd imagine Shadow Warrior might be easy to sell here, seeing as Duke 3D is, but I can imagine there may be some hang-ups. As to Blood, I'm utterly clueless.

I doubt it. Atari owns the rights to them, and they are not interested in re-releasing it. Throughout the years the fans have contacted them trying to get them to re-release the game, repackage it, etc, with no reply from them.
I'd like to see lesser known build games like Powerslave, Witchaven 1 and 2, Extreme Paintbrawl, and the commercially released duke3d mod ww2.

That's a shame. I'd still love to see them here.

Shadow Warrior might not be as known as Duke Nukem but still an awesome game :)
Some of the games im hoping GOG.com will release;)
* All Duke Nukem expansions. ;)
* Shadow Warrior.
* Witchhaven.
* Blood 1 & 2.
* Realms of the Haunting.

I'd like to see Powerslave, such a fun game, which was located at ancient egypt before serious sam. :D
Speaking of Intracorp game, I'd like to see corridor 7 and the prototype of corridor 8 too.
