Oooh, I know this one. Actually, I think there are a couple of SF references, though the others are more out in the open.

I entered with the one I would consider hidden, but as Ois says there are defiantly a couple more in the game.

For this and future contests, at the end of the contest, please post the correct answer. It is interesting to know if you got the correct answer or not.

Agreed! :)

I sent my answer in, but foolishly forgot to enter my username. *facepalm*

Send it again, it's no big deal. :)
Anyway I think they can identify you by email address, but just in case send it again.

You have to do that? I figured they would just respond to the email address to let you know you won and ask what your username was.

As stated before, please also post the correct answer when announcing the winner.
I think I'm not the only one that would like to know if I got the right answer.
Please...

Seconded, It would be nice to know if I was even close in my guess.

No, it's done by e-mail. I won the beauty contest and didn't give them my username. All good. :)

Phew, thanks for confirming that chautemoc :)

Holy crap! That's two contests in a week! I must be getting the luck of the Weclock here. Thanks, GOG! :D
I didn't put in my username either. I just used the same email address that I used to sign up with GOG. So, I'm pretty sure it's just like Iuliand said where they identify you by that email address.
And I'm actually curious how many other people got this as well. I only barely remembered it from when I played years ago and had to reinstall the game and go exploring with God mode on just to remind myself.
The sci-fi reference is from Babylon 5, an old, but really good TV series from the '90s. If you fully, and I do mean fully, explore the Dryad Forest, you should find a lift that takes you to some underground cave at the end of one the pathways. The first area you drop down in will have some large writing on the floor that says when read vertically, "If you go to Z'ha'dum, you will die." Then in the next room, you'll see one of those ships from the planet Z'ha'dum, called Shadow vessels. And of course, if you get too close, you will die. Shoots out some purple laser beam that instantly kills your character. I feel sorry for those people that were playing hardcore characters when they discovered this.

Ok I have never found that on any of my multiple playthroughs. I thought it was the Saber of light(star wars light saber reference) hidden in the monestary in the desert.

I put in both shadow and saber reference, though I had to use wikipedia to refresh myself on the spelling of Z'ha'dum, and what it was. Long time since I've been to that area and a long time since I watched Babylon 5.
Apparently, If you go as a group, can spawn a lot of pets or, have a recover after death chance; you can survive and get a item guarded by the ship. Never managed it myself though.
