What Is The Scariest Game Ever Made?

It's almost Halloween, and we want to know what game scared the pants off of you.

In the interest of getting into the holiday spirit, we thought we'd ask you, our fine readers, about the scariest game you've ever played. Did Silent Hill give you nightmares? How about when Resident Evil made you jump? When did Eternal Darkness get into your head? How soon after starting Dead Space did you start holding your breath?

And if you're feeling really ambitious, tell us what moment in that game really sticks out above all the others in the world of frightening interactive experiences.
