The genius of this module is that while it follows the KISS principle impeccably, it offers great scope for customization and extension.
A novice Storyteller need only deal with a limited range of variables – a single adversary with a simple goal, based in an isolated location. Defeating the adversary requires the skills of a diverse but familiar range of character types who are well-represented by the pre-generated PCs. No possible scenario will ever cope with every combination of characters that a player group will come up with, but The Hunger Within does a fine job offering a role to many of the likelier concepts.
The setting is sufficiently well detailed that it might become the home base of the PC group, with history, demographics, economics and notable watering-holes all covered - and interestingly so. (I particularly enjoyed the historical background). It feels like a real and specific place, not an “everywheresville”. But with a little work, it could easily be transplanted to America’s eastern seaboard or Eastern Europe and the scenario would still work perfectly.
The scenario would also work well in other contemporary or near-contemporary horror/fantasy settings. It has a somewhat Cthulu-esque feel in any case, and a new Keeper looking for a start for his PC group may well find it ideal. It wouldn’t take a vast effort to use it in a Dresden Files or Buffy game either, either.
So, it’s flexible, adaptable and offers a “conventional” PC group lots for its different members to do. But it doesn’t have to stay simple; the background is rife for potential hooks for expansion, with the town’s past, the villain’s past, and the nature of the entity he’s associated with all ideal for exploration.
I also found it very atmospheric. Though it's contemporary, in my mind's eye, I pictured it in black and white, with lots of sinister fog, like a supernatural version of a Basil Rathbone Sherlock Holmes.
The writing style is clear and crisp, easy to follow and with a high “useful RPG stuff” to word count ratio.
Overall, it’s a model of how to write an introductory scenario. Excellent value and well worth a look.
