An article about video games that began their lives in print wouldn't be complete without a mention of H.P. Lovecraft and his works on the Cthulhu mythos. There have been many games inspired by it, but I could only choose one.
Call of Cthulhu: Dark Corners of the Earth, a survival horror FPS, was inspired by a 1931 novella by Lovecraft called The Shadow Over Innsmouth. It follows the story of a gentleman who arrives in the town of Innsmouth to find that there have been a series of unexplained and secret events which have transformed the area into a spooky and barely inhabited ghost town.
Just like the main protagonist in the story, the player must piece together what has happened before going completely insane. In both the story and the game, you are confronted by Old Gods -- whose followers are as grotesque on the outside as they are inside and hell-bent on silencing you any way they can.
Development of the game began in 1999 with British indie developer Headfirst Productions, and it was eventually published by Bethesda. The game was released in 2005 for Xbox and 2006 on PC. Even though it is known for having many in-game bugs and some really difficult puzzles, it's still held in rather high regard by fans, and continues to be downloaded and played via Steam.
Lovecraft, being continually popular, is still in print to this day -- and you can find copies of The Shadow Over Innsmouth on Amazon from as little as $5.90. If you are interested in reading more about Cthulhu and the rest of Lovecraft's works, then there are some fantastic compilations available as well.
