OK, I have been starting a game and looking at the various City Sheets provided and noticed something was wrong. What finally struck me was that one "level" of sheet to be missing. To recap what exists, we have the High Level, Locations and Faces sheets, but these three do not make up all of how cities are organized or considered. Basically they cover the High and Low levels, but ignore the Middle. So, what is missing IMnsHO? A neighborhood/district sheet.
Cities are not generally a collection of individual locations and people, but rather a collection of neighborhoods. Look at Chicago and "The Street Level" is neighborhoods. The Loop, Gold Coast, Cabrini-Green, Lincoln Park, Uptown, Chinatown ... each has a different feel, mood and tenor. You might say "but those are just locations" but when you look at the sample City Sheet (Locations) on page YS38 what you see are SPECIFIC locations (with one exception). A business, a park, a bridge. Note that the park in the example is not a neighborhood called Federal Hill Park but rather a specific park by that name (many neighborhoods are referred to as "the <blank> Park neighborhood" ... yep, I look at neighborhoods & neighborhood names for a living). The only potential exception given is Fells Point / Canton which appears to refer to a specific location and an area (like Rush Street in Chicago used to be).
So, what I did was add an additional layer called City Sheet (Neighborhoods & Districts). I put in a choice box for Neighborhood, District, Municipality and Township, a section for Description, a row of 5 circles for "Threat Level" (0-5 ... to indicate how dangerous the area is generally considered), retained the Name, The Idea, The Aspect and The Face but added a section called "Areas Included" that allows for a list of a half dozen or so Locations (with space for Type to be listed). A Neighborhood is a collection of one or more Locations, a District one or more Neighborhoods, a Municipality (City, Town, Village, etc) one of more Districts, and a Township one or more Municipalities as well as the non-urban areas (Locations or Neighborhoods) in a roughly 36 sq.mi. area. What this allows if for the GM to say, for example, that the local INS building (where Karl Kolchak works) is near the border of Cabrini-Green and the Near North Side ... or maybe it is located in Printers Row just south of The Loop. In any case a group could use such a sheet to gather a number of locations in the same neighborhood and thus be better able to understand how the Themes work together and such (I may replace The Idea and The Aspect with Themes for this sheet). I fit only 6 per page, but it looks like it may work. I will see if I can construct and attach an image to this post.
Edit: Since the image insert worked the two samples are districts in a fictional city I am building for my own game. The first is a ethnic district (aka a Chinatown) and the other is something that I may or may not treat as a separate municipality (depending on player input). The former has a collection of locations that are neighborhoods and the latter has a collection of districts and highlights the most noteworthy neighborhood and business located in the area (aka, the occult bookstore). The Names field would likely list aldermen, mayors, and so forth that are not generally tied to a specific location.BTW, a link to a Chicago NBHD map
