I see you could adjust growth rate with the research rate, but I don't see where to adjust inflation.
It's a little lower, looks like this:
<iInflationPercent>10</iInflationPercent>
<iInflationOffset>-270</iInflationOffset>
Now what, exactly, these numbers mean, I'm not sure.. I am guessing a percentage of some inbuilt total and either a number of turns to wait until it starts accruing, or some threshold before applying maybe...
The above example is Marathon, as the game speed gets quicker the percent rises and the offset falls, probably to compensate for the falling number of turns.
Quick Settings look like this:
<iInflationPercent>45</iInflationPercent>
<iInflationOffset>-60</iInflationOffset>
EDIT
ach, need to adjust the turns too, never gonna have time to reach the modern era if research is slow but the years keep flying by at a normal pace...
Had to abandon a game wherein it was the eleventh century and us poor civs were just discovering calendar and currency...
That adds another pain in the assets, mucking about with the Month Increment and Turns per increment. Is there some kind of limit or guidelines to how these are supposed to add up?
Is it zero sum? Or can you vastly increase/decrease the number of turns and/or the upper limits of time (6500 AD?)
If you want, I'll spend some time experimenting with different set ups and let you know what I find.
