4. Killswitch
Killswitch was supposedly created by a Soviet gaming company Karvina Corporation in 1989, and only limited copies of the game were produced - between 5,000 to 10,000 copies. The game itself was rumoured to be a pioneer in the survival horror genre: you had to choose between two characters, a girl or an invisible demon, and the goal of the game was to navigate through an abandoned coal mine while battling demons and coal monsters. Unfortunately, no one ever completed the game with the demon, because upon beating the game all trace of it would be erased from your hard drive. In 2005, an unopened copy of the self-deleting game surfaced on Ebay where it was promptly bought for $733,000 by a man from Japan, who planned to document his play through of the game on YouTube. The only video that the man, revealed as Yamamoto Ryuchi, posted was of him staring at his computer screen and crying. This is again, is very likely to be a result of some well crafted Creepypasta.
