I like horror video games and films mostly. I think I mostly like playing/watching them so I can see people overcome harsh realities.
Some horror games I like:
Amnesia: The Dark Descent
Layers of Fear
Project ZERO / Fatal Frame series
SOMA
The Long Dark (not exactly a horror game but it has made me scream plenty lol)
Outlast
I'm not big on the traditional slasher type films like The Hills Have Eyes, or documentary type scary films like The Blair Witch Project and similar (I tend to find them very boring). I like the films with tension, and supernatural elements are often present. Horror films often make me laugh, and I enjoy seeing how the creative team work out how to tell the story of the film.
Some films I enjoyed were:
Paranormal Activity
The Conjuring
The Grudge
SAW
It Follows
The Taking of Deborah Logan
and Lights Out... since I'm bringing this film up, I found the festival short it was based on scarier than the cinema film. You can watch it here, if you dare, hehe!
Also, since bringing up YouTube, I also think this is freaky but cool:
I really enjoyed The Ring when I first saw it, and became engrossed with it so much that I read the novel, the manga graphic novels, watched most of the other films in the series (Japanese and American versions), and what not. I liked comparing them all, seeing what they changed to make the story work in the medium they were working with.
There's loads I still want to see or play...
