Some other great books and flicks for the post-apocalyptic/world falling apart theme:
- Dinner at Deviants Palace, by Tim Powers (hard to find but I seriously recommend this for any post-apoc fiction fans)
- The Gunslinger series, by Stephen King
- Logans Run (old flick, pretty strange, but has Vault-like people)
- 1984, by George Orwell (awesome, awesome book; not very Fallout-y, but democracy is crushed after WW3)
- Do Androids Dream of Electric Sheep, by Philip K. Dick (they based Blade Runner on this book, but the book is almost completely different - and better, including wastelands and all)
- 28 days later (interesting movie, more a zombie film than a post-apoc, but has a good deal of post-apoc elements)
- Escape from New York (film; again, not exactly post-apoc, but has Fallout-y elements; Snake's adventures through NYC are very Wanderer-ish, if the Wanderer were an evil-minded bastard)
