From publisher blurb:
Expeditions is a simple, single-page situation building tool for pulp-style adventures; fill in the blanks and off you go.
More expansive situation-builders can be found as part of Situations For Tabletop Roleplaying. In addition to being a general-use tool, Expeditions is part of a larger gaming platform. It is recommended that readers also look over Fundamentals of Tabletop Roleplaying, a basic run-through of "What happens in a roleplaying game?", and Mechanisms For Tabletop Roleplaying, a series of general-use "plug-ins" usable with most games.
