As I once indicated in
this posting here and explained in more depth in another posting, I don't find anymore right now

, corruption (including the idea of waste) and crime are simultenously linked to different things :
- wealth of the city
- wealth of the nation
- "tradition" of law enforcement means
- "tradition" of the governmental system
- size of city
- size of nation
Wealth just means, that you hardly can corrupt someone if you have nothing to offer. In turn, the wealthier your city/nation is, the more likely it is that corruption will happen
"Tradition" just means that if your people are used to face a good law enforcement force, they will less likely try to commit crimes.
Size just means that the bigger the community grows, the more anonymous people will be, making it easier to go away with "less criminal" acts, as corruption is regarded being a less criminal act in most modern societies.
This would eliminate the concept of ranking and distance, as the foundation date of a certain community has no influence at all on corruption or crime. The distance has, but just in an indirect manner, since distance influences not the corruption / crime, but the probability of having law enforcement in place and working.
So, even a distant city with "old, experienced" courthouses (to stay with this Civ3 example) would face lower corruption / crime than a city very near to the capital / FP / whatever, if not having a courthouse for a longer set of turns.
Additionally, the more wealth is available locally, the more likely it is to be confronted with corruption there. Additionally, the wealthier your nation is, the more likely it is to have an "overall" corruption percentage.
All this could easily be included, with just a counter for each city/law enforcement building - combination and a small calculation routine working for each city and on nation level.
The effect would be, that you would have a more "realistic" distribution of corruption which in turn would make your empire become more realistic.
Let's have a look at a C3C big empire: you have an effectivly working core and peripheric cities, which just don't do anything except for struggling with corruption and producing culture. For sure, those peripheric cities don't do, what they are doing (have been doing in history) in reality: providing the empire with military and / manpower on an overall basis.
In C3C, they just cannot produce units, because they loose too much of their production and the later units are just too expansive in manner of shields.
In reality, it is just the other way around - the more distant cities provide manpower to the empire, if their economy is less than the one of the main area.
Thoughts?
