I have just finished my first GC as Spain, it was really a tutorial for me since I couldn't get a DOW against the Mamelukes to practice war. I learned a tremendous amount about the game but one of the things that I don't understand is the inflation cost of manufactories. I had lots of gold mines and inflation got to about 22% before I could promote governors and keep it at 0%. The inflation cost of military units ranged from 33% for warships from 1492 to 1792, to 50% for infantry for the same period. However for manufactories, the inflation cost ranged from 655% for goods manufactories to 457% for fine arts academies for the period 1492 to 1792. It seemed that the cost went up every time I annexed another country. The cost doubled when I annexed Venice and stayed near that level for the rest of the game. How does the inflation model work for manufactories?
