All Plebians are supplied along one long road using the "forced walker" technique to supply each Grand Insulae (61 in all) with market, bathhouse, temple, doctor, barber, and library access. Other education and entertainment buildings also lie along the road.
The Palace block similarly uses forced walkers.
This is not the most aesthetically pleasing city. I built it primarily to see if I fully understood the use of forced walkers, and also because I had never built a city that works like this one before.
Promotion has already occurred, but was delayed for 5 years. The game will end in roughly six months.
I owe a great debt of gratitude to the following C3 Heaven forum members: Goonsquad, Joshofet, Philon, Duan Xuan, and Brugle, whose many informative posts taught me the tools necessary to build a stable and profitable city like this.
