Great googly wooglies!
New map:
The main change is the loss of the Market Development Charts as described below. The little yellowish spur bits are where the markets that will be priced on that island are placed during setup in a stack (must remember to update rules to that effect). Each small yellow circle contains a number which defines how many markets are to be placed there during setup. Simple!
An interesting aspect of this is that I can tweak the numbers of markets in specific locations downward to change the weighting of the graph if needed.
