I'll be getting these this weekend. I've been wanting to buy them. I think it will be a lot of fun to play these with a joystick like an old arcade game.

I love the old Apogee games, but can't help but believe that the reason for this promo is because of the very low sales from these 3 titles. After all, duke3d isnt included. : P But still, it's good that this way more people will become fans of these games. : )

I was pretty tempted to buy RotT because of this but I think I'll hold off for the Rainbow Six game coming up.

Rainbow Six might still be months away.

This is another reason to finally try the Blake Stone games. Buying now.

I can't help but be a bit disappointed about which games GOG has from Apogee so far. I mean, the Doom clones might not be bad, but they are not the games I remember playing from Apogee way back when. Where's the legendary platformers we rubbed in the console-boys faces back in my youth - where's Crystal Caves, Secret Agent, Cosmo's Cosmic Adventure (heh), Duke Nukem 1&2, Monster Bash, and Hocus Pocus; or the equally great shoot-em-ups Major Stryker and Raptor? Those are the games I want to see, not Blake Stone which I totally ignored back then and now, RotT isn't bad, but it's no Monster Bash (after all, shooting zombies with a peashooter with a pyjamas-wearing hero NEVER gets old)!
In short: where are the true Apogee classics, and when we can we expect to see them? ;)
I wouldn't mind 3D Realms "Terminal Velocity", either...

ask apogee, GOG can only sell the games Apogee allows.

Some of the games you mentioned like Raptor , or Terminal Velocity weren't made by Apogee, they were only published by them. Their availability in GOG doesnt depend on Apogee but on their original developers.

Actually, it depends on whatever publisher owns right to them now (maybe it's Apogee).

3DRealms (formerly known as Apogee) are offering many of those games for sale on their own website, so I assume they have some control over the distribution rights.
TO 3DREALMS: RELEASE MORE OF THE APOGEE TITLES ON HERE; DO YOU HEAR ME!

Rise of The Triad is finally MINE!

I want Death Rally. And Terminal Velocity too.

I want Death Rally. And Terminal Velocity too.

They can only sell them on their store, they dont have a say where else those titles can be offered. You'd have to ask Mountan King in the case of Raptor, or Remedy in the case of Death Rally.

I just had a look at the 3DRealms online store and their pricing is very strange and completely inconsistent.
For example, the games that are released here for $5.99 sell there for $5.99 too, with the exception of DN: Manhattan Project which doesn't seem to me on the store at all.
However, most other games sell for more. This includes such highlights as the 1992 release Math Rescue / Word Rescue for $10. Secret Agent is a game from 1992 that costs $15 - while ROTT from 1995, vastly superior in all shapes and forms, costs $5.99.
Most other games costs $10 - except Wolf3D which costs $15, or three times as much as the game is currently selling for on Steam.
In their store they do keep the option of sending you floppies, but who wants that unless it's a shrinkwrapped collector's item for $59.99 off Ebay?
Geeze 3DRealms, get your games on here and fix your pricing to consistent and logical levels and your games might sell some.
