Concept: “Roll 2d6 and meet a stranger”
Content: A throng of bizarre personalities, hirelings, bystanders (some with personal connections to each other); also includes some locales and rumors
Writing: Suitably dark and disturbing with plenty of rimshots
Art/design: Fairly straightforward layouts with art that brings a strong arcane-mechanical flavor to the table
Usability: Very useable, and motivates you to do so

Concept: “Let us return to the city where we may meet visitors from other places … and kill a few of them.”
Content: More NPCs, hirelings, rumors, and sites to populate the city
Writing: Descriptive text provides motivations and hooks, with many unique special abilities
Art/design: A mix of colorful weirdness for major NPCs and more subtle, baroque art for the rest
Usability: Will often refer you to Strange Citizens, so make sure you keep that volume handy
