If there's one way that homebrewers differ, it is in the size of their cities. Some are comfortable in sparsely settled frontiers or primitive unsettled times, and other prefer to run games in vast cities that encompass worlds and planes. Which one are you?
Did someone call my name?
Urbis, the setting I've been developing ever since it was rejected by the WotC Setting Search features many cities with populations in the millions - the biggest known city,
Atalus, has about 5,600,000 people within the city proper.
In fact, justifing cities this large within the D&D framework of rules was one of the main design goals of
Urbis. Fortunately, this was rather easy.
It started when I took a look at all the magic within D&D and asked myself: "With all this stuff out there, why do most of the D&D setting still have feudal power structures and settlement patterns?"
Then I had to come up with a reason why rulers would want to build such large cities. Thus, I came up with the concept of
Nexus Towers - enchanted towers that can draw upon the life force of all who live near them and convert it into magical energies.
Now we have a nice, magical arms race. If you have a city with
Nexus Towers, you can produce lots of magical items or cast really big spells. If you don't, your neighbor who
does have them will wipe you out.
If both of you have
Nexus Towers, the one with the bigger city tends to win, as he has more people to draw life energy from...
After voting, let us know how your society supports itself. What does the citizens of your ubercity eat and how does it get to them?
The usual - meat for the well-off, gravy for the unwashed masses (though the wealthy can afford some
amazing delicacies...).
What's different in
Urbis is that the food isn't grown on some mom-and-pop farms, but huge plantations with whole armies of seasonal workers. The growth of the plants is frequently supported by the magic of
Nexus Towers as well - there's a
spell that effectively casts
Plant Growth on a 14-mile radius...
The food goes to the cities either by ship (on canals, rivers, or the ocean) or railways pulled by stone golems (you didn't think these had only uses for combat, did you?

).
How do the people of Sagebrushville get specialized items that cannot be manufactured in small villages?
Same way the people in the city get their food - just in the opposite direction.
Oh, and you can be sure that the city-based mechant cartels make certain that only
their wares are sold in even the smallest village...
