If you want to run a city-based campaign in Dungeons & Dragons (or any other clones/hacks), then I have a few zines and blog posts you may find useful.
Plus, I have added a couple of books I have bought and found quite useful for D&D city-based campaigns.
The first four zines are all focused on building out your city, while the final two can help you create some random tables, and deities for your campaign.
The blog posts are about using alignments to add flavour to your cities, and also how cities could restrict spellcasting via laws and bans. All for the safety of its citizens.

City of Golotha
I just bought another Harn supplement. I am loving these books – so detailed with heaps of D&D inspiration! Get City of Golotha over at DriveThruRPG.
Town Builder
This looks pretty darn cool! A heap of D&D fantasy businesses to drop into your favourite town. Features an adventure hook, items they sell, fleshed-out NPCs, rumours, and more! Get Town Builder at DriveThruRPG.
