Great mod.
Is there an explanation somewhere for the "Additional Policies Needed to Unlock" for Wonders? This feature keeps tripping me up. I can't figure out how to tell how many policies are needed prior to researching a tech. So, for example, trying to beeline Trade for Petra during a desert start, getting there, and then seeing Petra grayed out because I don't have enough policies unlocked. Not understanding when a wonder has additional requirements is making it very hard to be strategic.
When you look at the tech tree it should mention it like this:
Cost in hammers
Required techs
Amount of policies required in total with the amount of policies you currently have in parenthesis
For example:
Cost: 123
Prerequisite techs: Calendar
Policies required: 3 (Have: 0)
That's for Pyramids on quick.
Keep in mind that openers count as a policy.
