>Any tips for building a realistically dense city, preferably industrial revolution era?
A hallmark of industrial revolution cities is ramshackle multistory living. Industrialization always drives huge numbers of poor people from rural settings into urban ones (plus drives tons of immigration), where they hastily build outward until it becomes too expensive, then start building upwards, resulting in shoddy slums of apartment buildings packed to the brim with poor families. This has happened in nearly every nation that has industrialized, for anywhere between a few years to several decades. Much of India is still like this and up until recently so was much of China. Suburbs don't come until much later (and even then, only in dysfunctional neoliberal states, where the cities subsidize them).

And if you leave the cities, industrial age rural towns looked much the same as they did prior to industrialization, just with an industrialized building here or there, like a factory or power plant.
