A few months back I saw the Roleplaying City Map Generator mentioned on a forum, but the website hosting the application seemed to have disappeared. Fortunately someone found a copy of the website (and the application) using the internet wayback machine which periodically archives websites of note.
That forum thread lead me to write my random dungeon generator reviews and was an early inspiration to me for the Hexographer application I’m writing.
Because the Roleplaying City Map Generator is noted as 100% Freeware, I’m hosting the download file on a page here at Inkwell Ideas. The only two drawbacks to the application are: it only runs on Windows, and the source code isn’t available for someone to pick up where it was left off. (And if it is being actively improved by someone, please post.)
I too have checked this generator out. I has a lot of potential. I few tweeks and it could be very good! I hope someone fixes it.
