I launched a collective Spooky City set for Halloween and Anxiety Wizard edited it and used it to post a introduction to his City Generator Kit.
I made a video where I generate a Spooky City using the set: Generating a Spooky City!
Here is the cleaned up map:
As a experiment I zoomed in a district and applied the landmark rules to create neighborhoods (this is how I generated the secondary streets). To color the neighborhoods I mixed the district theme with the themes of entries I rolled on the districts table. A other possibility would have been to roll random encounters for each neighborhoods to color them.
