Reading, or rereading, personal "foundational works" is pretty awesome. I can very clearly attribute my interest in D&D to Joel Rosenberg's The Sleeping Dragon, in which a group of college gamers is transported to a fantasy world by their gamemaster/professor. I also encountered the 1e Monster Manual around that time, and made up my own system using what was noted in the novel (levels started at A and went up) and the MM. Alas, many of my notes* flew (literally) out the window during a drive from NH to Alabama for a Christmas vacation. Fortunately, my older AL cousin played ACTUAL D&D....Finished Thieves World's Wings of Omen. Thieves World is one of my foundational fantasy works, having read it a little too young, so it's hard for me to be objective about the series.
(Side Note: The fate of one of the characters early on in the book STILL stands out in my mind as a stellar example of This Is Not Like Other Books; Here There Be CONSEQUENCES! I love this whole series, to be honest.)
As a teen in the mid and late 80s, other serious influences were Guy Gavriel Kay, Robert Holdstock, CJ Cherryh, and a few others I can't recall right now. I feel like my fantasy world should be a lot more cerebral than it actually is....
*I had Ewoks as a PC race, I remember that much. And stats were on a 1-6 scale.
