Plus, unlike in AE, things aren't really explained to you properly in AO at first, just that you have to escape and run away from things that want to stab their beaks through your chest, shoot you in the back, or bite you in two - And all of that in an environment where you can't see clearly where things are, only shadows (at least in the Stockyards, anyway).
So I vote for AO - It was just the most atmospheric out of all the games. AE has creepy concepts, but the atmosphere is brighter, including the music. Besides that, you're not running away from things - You're infiltrating industries to rescue people, or simply trying to get from A to B. SW isn't creepy at all either, because even though you're constantly outnumbered, Stranger is a tough character and even when naked and stripped of everything, isn't ever really that vunerable to those that wish to hurt him.

AO was the creepiest for me when i was the kid, the opening noises always freaked me out xD

I made a post similar to this in this thread a few days ago, but it would seem I forgot to post it and closed down firefox. You said it much better than I did anyway. :p

People are far too critical of GBA MO. Okay, I wouldn't hold it up on a pedestal, but for Oddworld fans it's another game with our favourite characters in our favourite Universe. If anybody actually gets a chance to play it, please do. You'll see it's not as "creepy" as you're all making it out to be. :confused:

Stranger's Wrath.

i wud say strangers wrath. the whole having an octigi on your head controlling u while ur alive underneath creeped me out. yuck. poor steef

I wouldn't actually say that SW is creepy, it's just full with suspense, but for that matter you are right, the octigi are somehow creepy :D

but I still think AO is the creepiest game so far :p

I would have to go with AO because of Rupturefarms and the Stockyards. I mean, with the Brewery in AE, it was just industrial looking. In AO there was blood all over the walls, big hunks of meat falling from the ceiling, the darkness of the stockyards. I remember when I first played the game at the age of like, 6, I was so scared of the game that I turned it off when I got to Paramonia... So, I think that AO was definitely the creepiest.
