P.T.'s actually the only game that's ever had me like that, which is a testament to how well it's done, especially just for a little promo teaser for an upcoming game. I love the original Resi Evil, Silent Hill, Fatal Frame 2: Crimson Butterfly, etc. - I really enjoy the dark atmosphere those classics create, just like I do Dead Space, TLOU and Alien: Isolation more recently. But P.T. starts turning really discomforting as you go further, it gets so fucking tense and foreboding that it can actually become not such a pleasant experience to put yourself through. It's quite rattling, really - the whole tone of it is deeply unsettling and a bit warped.
I would defo highly recommend it, but it of course has to be done at dead of night, with all its sounds up close in your ears from all angles. Both that chilling sound design and the sheer graphical realism probably add an extra freak-factor for me, because the 'videogameyness' of the golden oldies does help provide a certain distance, however well they still ramp up the tension and deliver their scares. It's probably the only game that's ever truly scared me, as in had me so sweaty-palmed and on edge I had to just leave it, and have been wary of returning. It isn't about gore and jump-scares, it just drips with a heavy sense of dread and wrongness. Hard to describe really, but don't spoil it for yourself by watching vids on youtube or whatever; I dived in completely unawares, and got the full impact.
