World's Largest Dungeon coverAdventurer! This revived May 2019 bundle of tabletop fantasy roleplaying supplements and adventures includes The World's Largest Dungeon and World's Largest City, so we're once again 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 -- 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 this revived offer's World's Largest Starter Collection (retail value $72) as DRM-free .PDF ebooks, including Ultimate Toolbox, the d20 sourcebooks Empire, War, Mercenaries, Gods, Magic, and Relics, and the scenario collections Adventure I and Adventure II.

World's Largest City coverAnd if you pay more than the threshold price of $27.44, you'll level up and enlarge your already enormous purchase. This revival's World's Largest Bonus Collection adds 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.
