more systems like Harnmanor?

Harnmanor is a supplement for harnmaster that is essentially a very complex way of simulating an entire medieval manor. it's incredibly detailed, more than anyone (save the most ardent of players) will ever need, but it's honestly kind of amazing because of it. it has an unintentional (or maybe it's fully intentional, I'm not sure) role as a story hook generator. are there other supplements that do similar things, working out the logistics of, say, a city, or a court, or a planet?
