I'll give "Stage Limits and Thresholds" a read. I had no idea that education level actually affects the demand for certain types of industry (how logical). If this is a problem, it's a damn good one to have. Will have to keep this in mind for future development. And lastly, to reply to your third comment, my traffic congestion is fine--with exception of literally a single red dot in the corner of my city on an avenue. That's no surprise, since it connects another city of over 120k. I recently reworked the highway connection leading between the two cities after noticing that it was wonky, so we'll see if and how that alleviates the problem. The only other remotely congested component of my city's transportation network is a ground rail line that's colored yellow in the traffic info view. ~22k passengers max in a single lane, so no surprise there. Apart from the rail line and the red square on the avenue, traffic is as close to flawless as you could possibly achieve across the rest of the city. I think I can now call this topic answered! I'm somewhat satisfied with the explanation to the lack of development in spite of near-max demand in every sector that there is a regional cap limiting skyscrapers from appearing (I want skyscrapers, but the fact that lower-capacity buildings are appearing since I developed new zones means that my city and/or the game isn't catastrophically broken). I suppose that that's even somewhat realistic. Even if there was some other factor responsible for the lack of development, the city occupies almost the entire tile and it hasn't fallen apart. Given how complex and challenging this game can be, I consider just that alone a major achievement. And whether it was the no-kickout mod and the less abandonment mod as the sole cause or working in conjunction with another variable to eliminate dilapidation from my city, that problem's solved too. I'll be keeping my eyes peeled for problems, but for now my OCD may rest happily. Thanks for the help, resources and advice, guys.

Also, that Transportation Department income. Damn, damn, DAYUM SON! I am just noticing it. With that kind of income for transportation, I'm either a master at managing my sims's transportation needs or transportation income should be placed in a class of wealth in addition to R$ R$$ & R$$$!!! My city's monthly transportation income also vastly fluctuates. It fluctuates between several thousand dollars each month at least. It can even increase or decrease each month between + or - $0-10k! I can move the following question to a new thread if the moderators want that, but I'm going to ask--any tips to make my transportation income more stable? Perhaps it's to be expected in a rapidly growing city of this size, but I'll take any stabilization over these adolescent swings.

Yes, this is a mod. According to a youtube guide on SC4's game mechanics, it has "long been known" that the save and quit to region options can cause corruption of your city tile. Saving via ctrl-s or clicking the save icon which that shortcut refers to is safer. Stage caps? What are you talking about? Are you referring to the stages that limit the capacity of buildings--for instance, the population threshold that must be reached for skyscrapers to start developing? Or is this an entirely separate mechanic? Please be more specific, b/c unless the mechanic I described is not the only one that limits the number of skyscrapers in a given city, your explanation does not reveal what it is nor the puzzling reason why tiny houses would develop in a high-density zone in a city of over 143k (the pop threshold for skyscrapers is ~30-40k). See the attached photo for current tax rates in my formerly-80k-now-143k city.

And... why the extremely negative I-D & I-M demand?

UPDATE on the situation So I installed the no-kickout mod, 'less abandonment' & 'fixed underfunded notices' (however, b/c it's hard to see if installed mods actually start working correctly, I'm going to run another test to see if these mods actually started affecting gameplay). I also removed a neighboring city that I think contributed to the problem. Assuming the mods were functioning, as soon as I removed this city, demand in the 80k city for all job types increased overall, and my city's population has now increased to ~130k as well as the number of commercial & industrial jobs. Dilapidation and abandonment also mostly disappeared in all areas affected; that means that the removal of the connecting city was probably responsible for temporarily (I say temporarily, and I will say why shortly) solving the R$ & R$$ lack of development by the elimination of the infinite commuter bug, too-distant jobs, or both. Now, I say temporarily b/c the situation has changed. More development has occurred, but now almost all job types, as well as R$ R$$ & R$$$, are at maximum demand (see photos). With that high of a demand, I would expect even my high-density zones to very rapidly start exploding with development until the demand is satisfied. However, as illustrated in one of the photos, I didn't get skyscrapers. I didn't even get small high-rises. Instead, I get dinky houses. Unless my interpretation is incorrect or I'm missing something, that can only mean that there are not enough jobs that new development could reach; not that there are no jobs in the city--perhaps transportation is a problem (but I have many different kinds of transportation going across the city, so how would I pin-point where specifically within the city transportation is needed and what needs it?) I can't quite come to a conclusion b/c there are still too numerous variables.

I’m having quite a frustrating problem(s) with a city of 80k people. I will try to explain the problem(s) as linearly as possible. I’m having trouble precisely and concisely articulating the problem b/c it’s not clear at all what even I think the causes are, so please bear with me as I state the problem(s) I perceive as if I were trying to think it through. Will attempt to summarize all of this in a TLDR at the bottom. I would like as much as possible to at least eliminate enough of the problem(s) so that I can continue with this region and the 80k city especially; I do not want to start over. As you’ll see, there is a high demand for R$ & R$$ type buildings. It’s so high, actually, that R$ is as absolutely high as the demand graph can visually show, and R$$ demand is very close to being visually maxed too; with that high of a demand, I’d instantly skyscrapers would instantly develop—in explosive fashion. However, the only actively developing residence type is R$$$, and R$$$ type buildings instantly appear as soon as there is even slight demand for it. If I can get R$$$ to develop with little to no effort, surely the reason why such high demand for R$ & R$$$ will not be as easily satisfied cannot be b/c of desirability deficiencies alone. IF R$$$ buildings easily develop, desirability factors can’t be deficient enough to halt development of R$ & R$$. There are only a few reasons I can not think of that would explain this strange phenomena, but I don’t know how to test them. I’m first asking for advice on how to diagnose the problem. I ask this first, and now I explain what I think some of the following causes of this halt in development of R$ & R$$ buildings are that I’m asking for help to diagnose. Lack of jobs Poor transportation Desirability Taxes Infinite Commuter loop (I’ll get to this) I’m pulling my hair out as I try to determine the cause of the perceived problem. As I was testing to see if job availability is at least one cause of R$ & R$$ buildings not developing, I zoned I-D, as I knew that my demand for I-D was very high and lack of I-D jobs may explain why at least the R$ demand cannot be satisfied. So I zoned I-D in the same city, and sure enough I began to see R$$ appear in the city (oddly enough, since I expected to see R$ appear). It gets weirder, though. Near a cluster of high-rises, I had a fairly large patch of industrial zone filled exclusively with I-HT. I rezoned this to medium-density residential, and oddly enough the rezoned area began rapidly developing with buildings that could each hold ~100-300 occupants. But then–much of the buildings began to dilapidate and abandon. R$, R$$ & R$$$ alike, all dilapidating and abandoning. And when I’d click on the buildings, explanations for the abandonment was commute time and desirability. This is also not the only city in the region. I have a city of over 100k directly adjacent to it, and two other tiny cities (each lower than 10k pop), each of which connecting to the two big cities. That means that the infinite commuter bug could also be causing the dilapidation, although I have no idea how to see if it’s actually present. TLDR: So, all that said, here is the problem I perceive in as small a nutshell as I can say: R$ & R$$ demand is so high that visually R$ demand completely fills the demand graph and R$$ demand is just a sliver away from also completely filling the graph. But neither develops. And when I rezoned a patch of industrial zone to medium-density residential, many new R$$ (mostly R$$) buildings developed, but much of them quickly began to dilapidate and abandon. I also have more connecting cities in the region, which complicates the matter even more. I have no problem getting every job type to develop; just residential. And, while I can’t imagine that this would cause such massive fluctuations in demand across each city, tax rates are not consistent in every city.

Thanks. Will check these out.

I have recently posted an identical question in the general discussions for SimCity 4. It's quite quick, but almost definitely involves a detailed, complex answer. Does anyone know themselves, or if not then at least be able to direct me to some good documentation/resources about the simulation model for Cities: Skylines, and everything involved therein? How about the code responsible for this, and where it's stored in the game folders?

Two quick questions that requires a potentially complex answer: Does anyone know themselves, or if not themselves then at least be able to direct me to some good documentation/resources about the simulation model for SimCity 4, and everything involved with the simulation model therein? Where is the code stored for all this in the game folders, and has the source code been extracted?
