I understand what the impact is when I see something like 15% increase in food, or 25% increase in influence, but I often see bonuses such as +1 military or +2 food, or +1 increase in wealth. What exactly do those +1 and +2 bonuses translate into?
I assume there is some base number and those bonuses add to the base, but what exactly does having, say a +5 total bonus to food or wealth (for example) actually mean in game terms?
