First off, you can read this:

It may sound funny, but genres really CAN die. Point-And-Click Adventure is a prime example of a mid-90s staple which eventually went the way of the Dodo Bird.

The era of Survival Horror, as it was defined in the mid-1990s, is extinct; Developers who had delivered in years-past were forced by trend to incorporate more action elements, and less in the way of ambience or sideways creativity in order to deliver the thrills. Games like the original "Alone in the Dark", "7th Guest", and other contemporaries started a format which CAPCOM perfected with it's PSOne & PS2 "Resident Evil" series, or "Silent Hill" from that same period.

Both those franchises have switched to more action-oriented styles, for better or worse. I try to see the good in what's going on now, but I'm old-school at heart.

"Haunting Ground" is an excellent example of Survival Horror, because you have no real way of fighting the evils you encounter, so you need to figure out how to avoid them. Not being able to directly fight back, or to have combat which is (for lack of a better word), "clunky", to the point of not being able to spam attacks with machine-like accuracy, and breakable weapons or other reductive qualities to weaponry or general supply is a key element of the genre, it's one of the chief instigators of tension... The other half coming from a well-constructed landscape, with creative audio-visual things going on...

"Eternal Darkness: Sanity's Requiem" is almost completely unique for one key reason. It's not the monsters, or the story, or any of the usual trappings; It's because the game reproduces what it's like to hallucinate PERFECTLY. Things will happen in that game which are mind-blowingly subtle at times, like a face looming out of the wood grain of the wall but when you turn for further inspection, it's as if it never existed, to the nerve-shattering tricks the game will play with the hardware itself... Survival Horror is about the feeling of fear, more than it is about a gorey, smoking-gun romp.

Although, those bits are fun too.

Survival Horror is the 'Clock Tower" games, "Siren", "Echo Night: Beyond", "Rule of Rose", "Fatal Frame" ... "Lifeline" ...

"Haunting Ground" is going to be slightly expensive and/or hard to find. As good as it is, I think it's a bit high-line to try for your dips into the genre. Istead, try buying a GameCube, and get "Resident Evil (Remake)", and "Eternal Darkness", both of which are excellent games, and a good introduction to the genre.
