Since inflation is now such a simple thing, it's only based on number of hurry production with gold that has been done recently (The number decays per X turn, X depending on gamespeed), I decided it should be a core economic factor that helps balance games regardless of options. This inflation is the ying to the yang that is treasury upkeep. Treasury upkeep push you to spend money, while hurry prod inflation penalize you for doing so.
Civic and other such modifiers to inflation, only modify the base value which is only based on the number of hurry productions you've performed recently.
Later, when/if I expand the inflation system to consider all gold spending and amount spent, I might put parts of it under the advanced economy option.
