At my local used book store, I recently picked up a copy of X3 The Curse of Xanathon.
I have not run the module and I haven't even read it in detail yet, but I thought I would share the few beginning pages because I think they are a hidden treasure.
The first few pages of the book detail the stocking of Rhoona, the city the adventure is based in. Rhoona comes unstocked/unkeyed (in fact unnamed on the map) and it is the DM's job to put the city together.
On the map, CIRCLES represent businesses, SQUARES represent taverns and the empty spaces in each zone are otherwise crowded with residences (described in each section.)
The sections are:
A - Old Town
B - Warehouses
C - Marketplaces
D - Temple
E - Temple
F - Barracks
G - Middle Class Residences/Businesses
H - Racial Sector
I - Ducal Palace
J - Dwarven Quarters
K - Upper Class Residences
So, after drawing the map, you roll on a random table and note down the name of a tavern or type of business for each of the circles or squares on the map. There are low class and middle class taverns.
