GP: "Horror in games has gone through some interesting changes over the years. Starting out as simple haunted house adventures (Haunted House and Sweet Home), horror games seemed mostly to stem from ideas formed in movies. As time progressed horror grew into its own massive genre thanks to the likes of Alone in the Dark and Resident Evil. Once it was known horror could be a very successful genre for games they were everywhere. Over the past few years horror has moved more toward the 'action' side of the spectrum.
Of course, there are still games like Amnesia: The Dark Descent which attempt to buck that trend. Even if you're not a horror fan you still probably know many of the titles: Silent Hill, Resident Evil, Dead Space, and others. In the spirit of Halloween, here's a list of some horror games which have rarely gotten a chance in the spotlight."
