In 1600 the Spanish and the Portuguese empires were forming a union called the Iberian Union that controlled uncounted colonies on 4 out of 5 habited continents. Under the rule of Philip III, at the end of the XVI century Spain was experiencing its rise.
Scale: Note that the scale differs in different parts of the map in order to emphasize the most significant regions. These areas are separated by borders.
Historical accuracy: 1. A few provinces in East Africa and India are absent from the map to make it more comfortable and playable. 2. Some geographic and political bonuses contain the same territories (like Granada and Emirate of Granada). This is impossible for a Warzone map, thus three insignificant alterations are made (Andorra is given to the Kingdom of Navarre, Catania is given to Naples, two African provinces are given to the Emirate of Granada).
Nice historicity. Perhaps as a reflection of the farflung nature of the empires represented, the different segments of the map seem isolated and independent of each other, and moving from one corner of the map to another can be a long slow slog. I suppose that's how it was in 1600, too.
