Originally this was a vast laundry list of novels that have had some influence on what inspires me when I run, read, write and play rpgs but it was rewritten to both A) reflect material that has had an enduring influence on my writing and gaming over a prolongued period of time B) parse it down somewhat since time is limited and there is only so much you can read on this earth.
What follows is a list of classical works of history and mythology, which serves as the primary inspiration for my gaming. This is supplemented by a fairly standard list of supplementary works, the majority being derived from Appendix N. Non-appendix N fantastic works are arbirarily divided into pre- and post 70s year of publication.
Of the Classics I will recommend Homer’s The Odyssey as the most all encompassing in terms of giving an impression of living in an ancient world of kings, honor, mythological creatures & the whims of fickle gods. Consider also Tacitcus’s Germanica or The Conquest of Gaul for inspiration for barbarian or evil humanoid tribes.
Of Appendix N I can heartily point to R.E. Howard, Fritz Leiber, Jack Vance & Abraham Merrit as the quartet of writers that strike most at the essence of what DnD is about. To this I would add the writings of H.P. Lovecraft, Michael Moorcock and J.R.R. Tolkien as essential supplementary material.
If there was one pre-70s author of fantastic fiction that I could recommend, it would probably be E.R.R. Eddison, whose mastery of language and stirring heroic tales are second to none.
In terms of post-70s authors, I would point to the writings of R.Scott Bakker as being most influential on my gaming and writing.
