Some impressions:
Dreadhalls- fuck that.
Seriously though, fuck VR horror. That is definitely the best medium to scare people, you know, short of reality.
Tried Dreadhalls today.
I felt sweaty all over + clammy hands moments after starting. Felt tense just looking around and wanted nothing more than to take myself out of that experience, to put and end to it. I got to an open area and prompted to check my inventory for oil. As I did, I looked a bit forward and to the right, and a hooded ghost/skeleton thing appeared and screamed. I found myself shouting in fright while simultaneously smashing the Escape key and ripping the Rift off my head.
VR horror... I'm not sure how well this will do with the general public. It's much more intense than any scary movie or game, to such an extent that it's pretty unbearable and I could see someone fainting or catching chest pains. I actually gave the game a second try; even with this large creature plainly in front of me and full mental awareness that it was fake and a "harmless game," it took serious concentration to not lose my wits and abort the game.
