I have no experience with computer games, but in my youth I loved the TSR board game Divine Right and the Lord of the Rings war game (a tie-in to the Ralph Bakshi animated movie, if I remember correctly), and I spent a lot of time in the late 1970s and early 1980s playing tabletop RPGs, mainly Dungeons & Dragons and Call of Cthulhu. More recently, Sydney and I have gone through a Magic: The Gathering phase and a Cheapass Games phase, especially The Great Brain Robbery. (A FSFS evening or weekend afternoon devoted to some game or other would be a fine thing.)

I strongly ditto all these already mentioned:

Ray Bradbury, Fahrenheit 451, The October Country, Something Wicked This Way Comes

Susanna Clarke, Jonathan Strange & Mr Norrell

Neil Gaiman, Sandman

Kelly Link, Magic for Beginners

Walter M. Miller Jr., A Canticle for Leibowitz

Alan Moore, From Hell and The League of Extraordinary Gentlemen

Christopher Priest, The Prestige

J.R.R. Tolkien, The Lord of the Rings

Doctor Who

Life on Mars

Star Trek (especially Kirk and company)

Star Wars (the real first trilogy, a.k.a. Episodes IV-VI)

Twin Peaks

2001: A Space Odyssey
