What is the scariest video game of all time?

So Halloween just flew by and I'm surprised no body asked this yet :)

What is the scariest game you have ever played and why?

Mine is definitely the infamous demo P.T.

That thing's just...nerve wrecking. The combination of claustrophobia, creepy room repeating and the fact that there's barely any music makes you listen a lot harder to things, and that's where it gets you.

Edit:

Some really interesting insights in the comments below!
I let ChatGPT summarize the top 5 scariest games out of this post.

Here are the results:

  1. **Resident Evil 7 VR*\*: Widely considered terrifying, especially for VR, with a strong focus on sound and atmosphere that builds tension. Many players needed breaks due to intense fear, describing the basement scene as particularly horrifying.

  2. **Outlast*\*: Known for inducing real fear, with chase sequences and lack of weapons creating a sense of vulnerability. Some players reported physical reactions like chest pain, and many couldn’t complete it due to overwhelming fear.

  3. **Alien Isolation*\*: The game’s AI and lack of resources keep players on edge, especially on higher difficulties. The alien's unpredictability, combined with survival mechanics, makes it deeply unsettling.

  4. **Amnesia: The Dark Descent*\*: Celebrated for its sound design, monsters, and eerie castle setting. Players feel defenseless, and some couldn’t bring themselves to complete certain sections due to fear.

  5. **P.T. (Silent Hills demo)*\*: Although just a demo, it is widely praised for its psychological horror and unsettling environment, leaving a lasting impact on players.
