Although Condemned is a pretty could horror. Scary as hell some of it.
Just bought Dead Space, so I'd imagine that may be a top horror!
Sure i get spooked when something that i missed or didn't notice creeps up on me, but thats it.
system shock series and the doom series would probably be in the list. Maybe even fear and resident evil.
But i have never really played horror games, i am more of an RPG, FPS man. But enjoy watching them, just find control can be annoying at times with them. Looking forwrad to Resi 5!
