Please note that I will be selling the 2nd edition map on the LWG website in the near future. Price $5. The map is probably the weakest part of the 1st ed. and the part that shines the most in the 2nd ed.
Also, the 2nd Edition rules and new Population Track (which was removed from the original map), will be available for download on the LWG website. You don't need the 2nd ed. rules because nothing has changed, but they were revised for better clarity.
So if you purchased the map and downloaded those two items all you would be missing is the upgraded marker counter sheet.
