I wound up with just over 3,000,000 fl in the treasury in my recent English campaign (admittedly the cash reserves started slipping backwards as I conquered more and more of the map and had progressively fewer trading partners....I tip my hat to you, Maloncanth, that is indeed a special effort.

Unlike Dazza and King Kurt, I prefer to get the florins flowing to add some flexibility...but I will concur with King Kurt, it would be immensely satisfying to get the "richest" message when you are in the hole - all of the AI factions must really be hurting.
