Just finished my first draft of Shore City, the sample setting I'm writing for Mystery Men!
I still have some labels to apply (the river, for example, is the Salamander), and then I need to add some of the highlights. Essentially, I'm going to write up a description of the city sections (Downtown, Old Town, etc) with random crime tables for each for patrols. Then, I'll add specific buildings and sites of interest, many of which will have adventure hooks of their own.
Of course, the street names are (almost) all comic book references, and a No-Prize will be awarded to anyone who can tell me which great American city the map is based on and why.
