Can't be too many games based on books can there? The only ones coming to mind are Flight of the Intruder and Megafortress. If I remember correctly, the Flight of The Intruder novel came with the game but it's been a while, late 80's?
There's lots of games based off books.
There was a Starship Troopers RTS in the late 90s (maybe early 2000s) that followed the books more than the movie.
Stalker was originally based off a short story.
Metro 2033 was based off a book series
The Witcher games were continuations of a book series.
SpecOps: The Line was basically Heart of Darkness in a different setting.
The original Rainbow Six was based off the book.
Red Storm Rising
The Hunt for Red October
and those are just off the top of my head.
