Video Game Trivia:
Playable Teaser, or P.T. as it's more widely known, was a surprise reveal for the development of a new entry into the Silent Hill franchise, known as Silent Hills.
It would've had Norman Reedus as the main character, and was supposed to be a joint creative effort by master of monsters, Guillermo Del Toro, and video game auteur and legend, Hideo Kojima. Unfortunately, the project was cancelled.
The popularity of P.T. however, meant that a number of tributes and homages were made and released, including Layers of Fear, Allison Road (which was never made, sadly), Visage, Home Sweet Home, Silent Descent, The Survey, God's Basement, Mists of Aiden, and a lot more. While they're not *all* based on P.T., it revolutionized and spearheaded a new movement of horror titles which you might call House Horror, or alternatively, Guilt Horror - where the twist is usually that the protagonist is the bad guy and is paying for sins.
