Balance changes for minor countries like Iran.
Previous version was targeted countries like Czechoslovakia - with better industry than many minors. After some tests I realized than it is harder to use all functions if you play Iran.
Iran has not good industry from start, so some decisions you can use only in late game.
So:

Decreased factory requirements from 8 -> 7 , 13 -> 12, 18 -> 17

Steel factory:
It was to OP
Increased PP from 25 -> 50, 25 -> 75

Urbanization:
Decreased consumer good by 30%
