Here is version 2.0 The surrounding six islands would be the home bases for each of the players taking the place of the universal port/market island in version 1.0 The galleons would enter based on the roll of a 12 sided die and leave by another roll of the 12 sided die. Thus if you rolled an 11, then a 12, the galleon would enter from space 11, then leave on space 12. This adds some randomness to it all but I don't know how I like it quite yet, or this map either.
P.S. Once again that picture quality!
