Background: This one huge metropolis for a D&D 3.5e campaign... looking to be, oh... 20 to 35 miles in diameter, give or take. Think more of a city-state, if you will.
Right now, my resources include the DMG, DMG II and the web enhancement for the DMG concerning districts.
Mind you, this is one grand undertaking.
I'm looking for some other resources concerning city-building for RPGs, especially D&D 3.5e. Books from other campaign settings can be suggested.
I haven't completely figured out about the layout of the city, apart from the central area being where the government meets and operates... though other suggestions will be taken into consideration here.
Oh, did I mention that The City is the only area that the PCs know? For as long as anyone can remember (at least 1000 years), most of what the population has known is The City. There's a buffer zone of another 15-20 miles before Outer Markers are reached, beyond which lies The Unknown... where scouting and exploration parties have gone, and only a few have returned. (I'm working on ideas with that as well.)
I'm going to need a city where PCs can work and have adventure, but they'll also eventually end up heading out of The City as well...
Ideas, comments, suggestions most welcomed.
