These maps ensure accurate resources and starting locations, fast loading times, and more room for the European civs.
They are based on a modified version of Robinson's projection: Europe is a bit larger and some other corrections were needed to fit the Robinson's map into a rectangle.
They come in two versions: 180x180 and 134x130. Land ratio for 180x180 is 39.7%.
Conquests version include starting locations for the new civs, marshes and volcanos, and the new resources.
NOTE (for Conquests only): as Ottomans and Byzantines share the starting location (Istanbul=Costantinople), Ottoman moved a couple of tiles SE, in the place where their first capital, Sögüt is. So, it is suggested to replace Istanbul with Sögüt in the cities list.
