Your favorite halloween themed game

Well, its dead on 12.00 am, 31st of October, 2009 in NZ so... 
 
Merry Christmas everyone! 
 
In addition to Early Christmas, it's also Halloween! So I figured in honor of this momentous occasion I'd get you guys to tell me your favorite Halloween themed game. 
Ok, when I say halloween themed, I just mean creepy, but perhaps Dead Space and System Shock don't count as Halloween themed, so at least try to stick to that. 
 
For my money, it's gotta be Medievil, the atmosphere and artwork were so sinister to me back in the day. Really takes me back to my time spent as a zombie... but thats a story for another day.

It's only the wee hours of the 30th here. o_O
WHAT IS THIS TIME TRAVELING SORCERY?!
And pertaining to the thread, I've been playing the first Diablo over the past couple of days, and man, it's still unbelievably creepy. Here's some music to give you nightmares (At around 1:55):
 

I'd definitely have to go with Medievil as well, I really loved the game.
Shame it never got a next-gen sequel, both the original PSOne games sold really well.. but then the series just vanished until the PSP remake, which was totally butchered.

I still absolutely love Bully and that has a Halloween part in it, so I feel that counts :P

I can't really think of a true "Halloween" themed game... I do remember playing Resident Evil 2 all night long with some friends.

Does a Halloween themed game exist?  (horror doesn't count as halloween either)

Early Halloween?  Aw, you Kiwi's are living the good life.  
 
As for a Halloween themed video game, well there is a crap-load listed on this site. LINK: Video Game Critics.  But for me, I'm going to go with one not mentioned on that site, Hunter: The Reckoning.  It's got zombies, werewolves, ghosts, vampires, and all other sorts of "things that go bump in the night".  It's not really scary, but the settings are traditional spooky stuff ranging from graveyards to rotted churches to eerie mansions.  It even has a Frankenstein-monster-teddy bear. 

Merry Christmas. I like to drink a lot on Halloween, I think that's important. Before heading out to a party, I'll be playing spin the bottle with bottles of Green Fairy while playing Vampire Savior on Sega Saturn.  
 

Really, no Left 4 Dead mentioned?  
 
that's what I'll be playing. That and Demon's Souls. I'm assuming you all heard about the PB WT in Demon's Souls all day tomorrow, right? 

Dead Space is one of my favorite games ever :D

Resident Evil 3 would have to be mine, or Silent Hill 1 for scare factor.

People actually play horror/dark games on Halloween just because it's Halloween? Really?
 
I'm gonna be playing Forza 3, Tekken 6 and Prototype while pretending that Halloween doesn't exist.

I usually just participate in the Halloween events for Guild Wars.

The Bedlam map on Killing Floor.

Kingdom Hearts 1 and 2. 
When you visit Halloween Town.. 

Not sure if it counts, but the Capcom "A Night Before Christmas" game, which was practically a Halloween game.

Does "Zombies ate my Neighbors" count?

I try to visit the delightfully awful world of Pumpkin Hill from Sonic Adventure 2 every Halloween.

Grabbed by the Ghoulies is my personal choice. I like me some Resident Evil and maybe Luigi's Mansion too though.

Obviously tf2, since they themed it for halloween.
