Neuromancer by William Gibson. Gibson started writing the book during filming of Blade Runner, which was released before his book hit the shelves, having an adverse affect. However, the book did and has become a cult classic for cyberpunk fans. If you like the genre, Gibson is required reading.

From a game perspective, one of the most fascinating IMO, was Syndicate. Released in 1993 by Electronic Arts and Bullfrog Productions, this game kept me at the computer for hours and was the reason I failed organic chemistry. I wish someone would come out with a modern release: https://en.wikipedia.org/wiki/Syndicate_(1993_video_game)
