I'm pretty sure the answer to this is "no", but here goes.
I am still working on a 7-day turns mod for CW2: 48 turns/year instead of 24. I think I can probably work out or fudge the issues I'm having with war/general supply, ammunition, money and conscripts. However, there are certain calculations performed per turn, and in many cases the numbers used for these calculations are already at their lowest integer values. Since I can't halve the values, the other possibility would be to halve the rate at which the calculations are performed. I know I'm making some wild assumptions here, like the rate of calculations for region loyalty or military control are set according to a rate or (very doubtfully) a turn index. But I'm pretty much at the end of what I can do outside of that.
I know that modifying the rate for these calculations could be easily abused, which is another reason I doubt it's available to the end-user. But I thought I'd ask before throwing my hands up in despair.
Numerous calculations are adversely affected by a turn-rate switch. Among them are:
national morale
victory points
loyalty
military control
foreign entry value
Any help is appreciated, even an official "no." Much thanks for your continued support of the game.
