I’m pretty picky about purchasing resources that purport to add to your game. I’ve been burned by more than a few that, when push comes to shove, I’ll never actually use at the table, either because they’re too cumbersome or because they do something I can just as easily do myself.
On the other end of that spectrum, C. Aaron Kreader’s 101 City Encounters is a book I can’t imagine running a city campaign without. Designed as a sort of mega random encounter table, the book offers a variety of interesting vignettes and situations a party might stumble across while traveling through a fantasy city. Some are relatively mundane (a funeral procession, a request for help unloading goods from a ship), while others offer tantalizing hooks that could lead to their own mini adventure (a carrier pigeon is killed and its note taken, a red devil appears and disappears leaving strange runes where it stood). Each entry includes suggestions for running the encounter and possible follow-ups.
101 City Encounters also includes a simple system for tracking a PC’s reputation in the city with a variety of groups: the Thieves’ Guild, nobles, the townsfolk, and religious temples. Higher ranks grant various benefits from each group, while lower ranks can cause problems when the party has to deal with the group in question. The system offers just enough detail to be helpful without becoming onerous to the Judge, especially with the inclusion of a custom reputation tracking sheet.
Although compatible with DCC RPG, the book is light on stats and can easily be adapted by a competent Judge to other fantasy systems.
101 City Encounters has already benefited my games and is highly recommended, especially if you’re running a DCC Lankhmar, Planescape, or similar campaign.
