Does anyone have a formula or table for the number of GPPs needed to produce a new Great Person in Fall From Heaven? (More Naval AI specifically, but I assume that this is something that that modmod doesn't change.) I think that it's different from vanilla Civ 4. How many Adventurers can the Grigori feasibly generate, taking into account their world spell, their unique buildings, Spirit mana, civics, etc? Obviously there's a practical limit somewhere well below the theoretical maximum; at what point(s) do(es) the costs exceed the benefits? What are the best uses for Adventurers? I like to turn the first one into a Scout and then Hunter to explore and capture animals, with the second becoming a Warrior and then Axeman.
