I remember playing this mod a few years ago, when city strength was something pops cared about, i.e. they became unhappy if it was too low, and this could be addressed by putting a garison unit in the city, building Walls etc. I liked it, gave me a gameplay reason to keep units at home and invest in military infrastructure even in cities safe from foreign invasions. In fact I even played around with implementing a similar feature in Civ4, because it does seem silly that a few cavemen with clubs could maintain public order in a mordern metropolis. What's the reasoning behind removing this feature?
On a different but also happiness related note, I read somewhere that a city's pops become unhappy if its relevant yields (culture for boredom, science for illiteracy etc.) are too low compared to the global median. Does this include civs you haven't met yet? Because it does seem kind of silly that e.g. the people of early 1400s Tenochtitlan who have no knowledge of foreign cultures beyond the ocean would feel restless all of a sudden when a cathedral in Europe is completed or a Chinese author publishes their magnum opus.
At any rate, keep up the good work! After a long drought I've finally assembled a proper gaming PC recently and gotten back into gaming, and I couldn't even finish a single unmodded game of Civ5 before I thought, "Oh this is a bunch of nonsense, let me see what Vox Populi has been up to instead beforeI rip what little hair I have left off in frustration".
