I'm developing a city for a Shadowrun campaign that I'm building and as part of it I started writing a sourcebook for the city. I'm doing it "kind of" in the Shadowrun style where everything appears as an electronic document w/ different people giving there opinions on everything.
The problem that I've run into is that I've got about 19 typed 12 pt font, single-spaced pages of text and I've already got 40 distinct voices on the threads giving their opinions on everything from which gang in the city is the most dangerous to which restaurant has the best tres leche cake. There's even some verbal sparring between posters (as really happens on the internet). The problem is that all of these posters either have worked or currently do work in the city I'm building. I know that Shadowrunners go where the work is so nobody really works exclusively in one city but most teams to have primary operating areas. Areas like Seattle or Denvers where there's just a lot of work to be had.
I always got the impression that there could be hundreds of Shadowrunners in Seattle (which I don't have a problem w/ per se, but I don't want my city to be that way)
So what I'm trying to figure out is in a city that's roughly 200 square km w/ a pop. of about 3 million (that's roughly 16,000 people per km): how many runners can the city support without them stumbling all over each other?
