Short version: I'd like to know how the various type of maintenance are calculated, and where the calculations can be modified so that I can tweaks some of the numbers. Also, there seems to be something weird going on with "number of cities" maintenance. Does anyone know how this works? I thinking of modding the game to make huge civs a bit less powerful, and increase the importance of having colonies etc. I figure the best way to do this is to increase some component of maintenance which scales super-linearly with the size of the civ. To get a feel for the numbers, I opened one of my recent save games in which I control a large part of the map. According to the financial adviser, civic upkeep:275 Number of cities cost:91 distance cost: 0 (state property) colonies: 0 corporations: 0 Then I switched to free market — no anarchy... here are the numbers on the same turn: civic upkeep: 295 Number of cities cost: 16 (???) distance cost: 142 Colonies: 16 Corporations: 30 I didn't realise that free market could reduce to # of cities cost... and what's even more weird is that in the city screen (in any city) the stated cost for # of cities maintenance was 7 with either civic. Based my number of cities (27), the state property cost of 91 was about right (taking into account "we love the X" day and courthouses). I have no idea where the free market cost of 16 came from. Anyway, it seems to me that increasing the # of cities maintenance cost is probably the best way to hurt large civs without unbalancing other things (increasing distance cost would just make state property even better. Increasing civic costs, although very tempting, may make "organized" too powerful, and I'm not sure if civic costs scale super-linearly anyway.) I guess my main question is this: what's going on with that # of cities cost under free market? ... and why does state property have lower upkeep than free market? I would have thought state property would have more organizational costs can free market — it would probably be more balanced if it was higher upkeep, too.
