I'm currently in the middle of DM'ing a city campaign. I've found it's quite a bit more difficult than a dungeon. I have the city mostly planned out (type of city, the ruler, the districts, centers of power, etc)— I used a generator to get most of that info.
My problems are these:
What do I say to the PCs when they get to a part I haven't written anything for or planned anything? Currently, when this happens, my mind races and I pause for a bit while trying to think of something. Any tips?
When the PCs need to get from point A to point B in the city, how do I describe the journey there? Currently, I say something like "you head south and then west" and maybe throw in a random encounter. How do you guys do it?
Any ideas or tips would be appreciated. I do have the Cityscape book, which is a great resource. I'm looking for how other DMs run a city campaign, and for any tips on how to make one successful.
