Adventurer! This new collection of tabletop fantasy roleplaying supplements and adventures includes The World's Largest Dungeon and World's Largest City, so we're calling it -- that's right! fight us! -- The World's Largest Bundle. A peerless 900-page megadungeon published in 2006 by Alderac Entertainment, The World's Largest Dungeon has 1,600 encounters -- a d20 System-based dungeon crawl that can entertain you for years. The City, with its quarter-million humans, dwarves, elves, humanoids, and (ahem) others, fits smoothly in most fantasy campaign worlds. And this offer adds Alderac's stunning 400-page Ultimate Toolbox, plus comprehensive d20 sourcebooks like War, Empire, Gods, Relics, Dungeons, and Dragons to give you over 4,000 pages of fantasy gaming goodness. The World's Largest Bundle! Yeah!

For just US$12.95 you get all nine titles in our Starter Collection (retail value $72) as DRM-free .PDF ebooks, including Ultimate Toolbox (previously in our November 2017 Worldbuilder's Toolkit 5), the d20 sourcebooks Empire, War, Mercenaries, Gods, Magic, and Relics, and the scenario collections Adventure I and Adventure II.

And if you pay more than the threshold price of $26.85, you'll level up and also get our entire Bonus Collection with four more titles worth an additional $75, including The World's Largest Dungeon (retail price $40), World's Largest City (retail $20), and a catchy pairing of two more d20 sourcebooks: Dungeons and Dragons.

[These are .PDF image scans of the original hardcopy supplements (2001-2007) with OCR (optical character recognition) applied. Text is clear and copiable. The text of World's Largest City is light; the rest have dark, crisp text.]
