My Own Private Appendix N

Zachary the First over at RPG Blog II hearkens back to the old AD&D DMG, specifically Appendix N (in which E. Gary Gygax Himself lays out the literature that influenced the development of his campaign) and challenges his readership to discuss their own private Appendix N: "What fiction has influenced your campaigns, play styles, and writings? If you want to include TV or movies, by all means."
