It's October 30tn. I have some time to kill tomorrow and I'd like to get into the Halloween Spirit. What's a good Halloweeny game that I could pick up from GOG?

edit- Misunderstood you at first Just read your whole post fully, and so I have to change my official answer to "I don't know "

Ghost Master.
Read the reviews and forum, but in short: It's a strategy game where the objective is to scare people & rescue ghosts, so it may fit your Halloween request. There is variety in the missions, though the first few are a bit simple which turns them off the rest of the game. I enjoyed it .

You could also try Darkfall or Obscure, both of which are horror themed.

I'd personally go for Waxworks

On GOG? Darkfall.

definatly ghost master, what is better for a scary night then a game about making a scary night for others!

darkfall for the scary atmosphere and ghost master for the fun of scaring people both are good games.

I haven't played it myself, but Obscure is quite high on my wish list.

Obsure is the closest you will get to a teen slasher flick in a game. Ghost Master I recommend as well. For a game not on GOG you can't beat a visit to Halloween town in Kingdom Hearts.

Vampire the Masquerade.

The Halloween Promo seems to be quite a nice deal for those who want to play scary games for Halloween ;-).

Bloodlines is cheap on D2D right now

only $4.95!!

I would suggest the original Manhunt. People wear masks and the game plays like a slasher flick...

Thanks for the advice. I decided to check out Ghost Master. I always avoided it because of the awful box art, but reading the reviews and reccomendations, it looks like a good time. And now that I have it, there's that horror game deal staring me in the face. I might cave in before the weekend's over. Never played a Horrorsoft game, but I love me some point and click....
