Featuring a foreword by gaming industry legend Monte Cook, Eureka contains 501 complete adventure plots usable with almost any roleplaying game, plus GMing advice and tools for making the most of every plot.

If you game once a week, that’s nearly 10 years of adventures, all right here in the largest collection of its kind ever published. Written by nine veteran game masters—the authors of the most widely read game mastering blog on the planet, Gnome Stew—Eureka is more than just adventure seeds.

Each plot includes a hook to draw your players in, an outline detailing enough material for a complete adventure, generally in the form of 3–5 meaty encounters, and any game mastering notes, plot twists, and advice you might need to turn that plot into a fun night of gaming.

Adventure hooks alone don’t give you much to work with, but fully developed adventures can be hard to personalize and fit into an ongoing game. Eureka is the perfect middle ground: We provide the main ingredients, and you decide how to prepare them.

Packed with ideas and inspiration, this massive collection is designed to be the ultimate adventure toolkit:

  • Fantasy, science fiction, and horror plots: 167 of each, all easily adaptable to multiple genres
  • Clear, concise game mastering advice: We show you how to adapt plots to other genres (effectively giving you 464 fantasy, 420 sci-fi, and 338 horror plots) and how to turn Eureka plots into full-blown adventures
  • The tools you need: Plots are grouped by theme, from “Revolt” to “Mistaken Jealousy,” and categorized by tags like intrigue, exploration, and combat-heavy
  • Four indexes: Quickly find a plot for any situation by genre, tag, title, or author
  • No game mechanics and no proper names: These system-neutral plots are simple to use and easy to personalize to your game
  • DRM-free, fully hyperlinked and bookmarked: We've made Eureka as user-friendly and GM-friendly as possible.

If anyone purchased this product, please share your opinion. I have not examined the book, only listened to an interview on the 3.5 Private Sanctuary podcast. I'm hesitant to spend $17 on a PDF sight unseen, but I could use some inspiration for side quests and adventures.

EDIT: Here's a preview:

Eureka 501 Preview

I liked what I saw, but I'm still not sure.... It's 300 pgs., roughly 1/3 of the book is fantasy plots, although others could be converted.

If you're not sold on the basis of the preview, I won't try to sell you any harder -- it's a good representation of the book as a whole.

But I will recommend checking out Eureka's rave reviews, and I'll mention that while 167/501 plots are explicitly fantasy, 464/501 plots are easily converted to fantasy (and the GMing chapter shows you how).

One of our explicit design goals with Eureka was to produce a book that would be useful to just about any GM, including folks with a favorite genre and folks who primarily play a single system. There are a ton of plots in the sci-fi and horror chapters that can be adapted to Pathfinder, if that's your game of choice.

Awesome! This is a great great book, but the PDF will add quite a bit of usefulness. I might just make a filterable version of the index so you can narrow down by multiple themes.

One of my friends helped write this book, and he (along with the book) is super awesome. I highly recommend checking it out. :)
