OMG, I played this demo last night, I seriously had to switch the console off, it was just so scary.  I felt totally immersed in the environment; everything seemed real, the little map was so detailed. The game maker had the measure of me - I sat defeated, my warm urine seeping through my pants onto my already soiled armchair.  In short, it had me screaming like a girl.  I salute you Mr Kojima.
