In November 2016 we brought you the all-new Old School Revival Bundle 4, celebrating the neoclassical movement to recapture the spirit of roleplaying’s earliest days, the Old School Revival. This fourth annual OSR collection — by far the most successful installment of the series so far — featured vivid campaign settings, strange megadungeons, unsettling modules, hundreds of maps, and — ta dahhh! — the new edition of Tunnels & Trolls!

There were no less than eight titles in our Starter Collection (retail value $42.50) presented as DRM-free .PDF ebooks:

• Deep Carbon Observatory (False Machine, retail price $10): A harrowing underground quest by Patrick Stuart (Maze of the Blue Medusa) illustrated by the redoubtable Scrap Princess.
• The Pod Caverns of the Sinister Shroom (Expeditious Retreat Press, retail $6): The first Advanced Adventures module by OSR pioneer Matthew Finch (Swords and Wizardry).
• Castle Gargantua and Mad Monks of Kwantoom (Kabuki Kaiser, retail $5 each): A Gothic megadungeon and a spectacularly fun Asian campaign sourcebook.
• One-Page Dungeon Compendia 2013-2015 (Shattered Pike Studio, total retail $9): These three official collections present 270+ entries in the popular One-Page Dungeon Contest. Sales of these collections support the contest.
• 2014 Dodecahedron Cartographic Review (ZERObarrier, retail $7.50): Dyson Logos, archmage of dungeon cartography, gathers works from his Dyson’s Dodecahedron blog.

Those who paid more than the threshold (average) price also got our entire Bonus Collection with eight more titles (retail value $80.50):

• Deluxe Tunnels & Trolls (Flying Buffalo, retail $20): The latest and greatest edition (complete! 386 pages!) of Ken St. Andre’s 1975 classic. Includes the Gamemasters Screen (retail $1).
• Dwimmermount (Autarch, retail $10): The Labyrinth Lord version of Autarch’s colossal 400-page science-fantasy megadungeon and campaign setting.
• Yoon-Suin (noisms, retail $9): David McGrogan’s acclaimed roll-your-own campaign setting, a languorous Yellow City in a remote Purple Land.
• Misty Isles of the Eld (Hydra Cooperative, retail $12): Chris Kutalik’s acid fantasy mini-sandbox standalone sequel to Slumbering Ursine Dunes.
• Chthonic Codex (Lost Pages, retail $18): Paolo Greco’s unique campaign setting of cutthroat academic politics in a magical university.
• Tunnels & Trolls: Goblin Lake (retail $3): The new deluxe version of Ken St. Andre’s classic solitaire adventure.
• 2015 Dodecahedron Cartographic Review (retail $7.50): The latest giant map collection from Dyson Logos.

That’s a total retail value of US$123, worthy of Treasure Hoard Class IV and a +10% modifier on the Miscellaneous Magic Items table. Ten percent of each payment (after gateway fees) went to this offer’s designated charity, Doctors Without Borders.
