Man, this game lets Doom 3 and F.E.A.R. far behind, and it's so well done, at the very beginning, when there is nothing following you yet, the mere athmosphere is enough to get duck under my table out of fear. The only little thing that bugs me though is how fast the oil lamp drains, in real one would have light for a long time when left with a bottom of oil. But the sanity loss, it does quite match with how I would feel in such a situation, dunno if I'd hallucinate, but then Daniel also lost his memory so that adds to the confusion I guess, nice cocktail for insanity.
And yeah, as soon as I run into something scary, I find myself exiting too, but also left with curiosity. So far I LOVE the touch of detail with the piano. I walked passed by, the lit over the keys was closed, and when in the other room, I heard the piano being played, when I come back, the lit is left open. Now in real, THAT would make me loose my sanity.
