This is the City you've all been waiting for. The holy grail. 600 Grand Mansions! Marvel at its elegant symmetry and centralisation of wealth and services. This city has been 6+ years in the making. Its fully functional and totally legit - Except for one small detail.. I had to disable the fire/collapse script, as it is impossible to build a city this big and not have your firefighters running around the city like headless chickens and causing the entire city to go up in flames! So I hope you will forgive that. If you are a purist, then feel free to add a few more pleb houses and build prefectures and engineering posts everywhere - there's still just enough room to include them.
