And here's a basic concept of the Old World:
Things to note:
1) All greenish countries are Ottoman vassals, except for Ireland and Rome.
2) Venice is the blobbish thing in the north of Italy.
3) Courland's colonial efforts in Siberia defaulted to Poland after the latter came under Swedish rule.
4) France is a dominant power on the Continent, but will likely suffer heavily due to Basque-Catalan and Dutch-Belgian nationalism. It also enjoys a weak colonial position, but this is its own doing (in this timeline, they have been chummy with the Venetians and Iberians to counter the German nations, and later Russia).
5) The German countries are Prussia, Saxony, Hessia, and Bavaria. (These may represent alliance systems rather than polities.)
6) Japan has already been opened, and the Venetians and Iberians both have treaty ports. The same may end up applying to China (I haven't decided on who would get what yet, though).
7) Oman is a major imperial power in the Indian Ocean, but is uncivilized.
8) The Danes recently split off from a greater Scandinavian union; the Danish and Swedish colonies were once unified and the ability to unify them again will likely exist somehow.
9) The Suez canal will likely be open at the start of the game. (An Ottoman ruler decided to create one, leading to Ottoman - and, to a lesser degree, Omani and Venetian - economic and political power far greater than historically true.)
8) The red areas of India represent Rump Mughalstan and its vassals. Other red nations are Bohemia and England.
9) I may remove the White Sea port provinces from Russia and give them to a satellite nation in order to represent their general uselessness as significant ports of call - and in order to force the Russians to expand to the sea by military means.
10) Iberia is a central union, but will almost definitely have to face a rebellion within Portugal and the colonies.
11) Brazil may have a nation in it when I get around to messing with the New World; I am most likely to give Prussia (Humboldt is the discoverer of America in this timeline) and the British nations (traditionally snubbed from the race to colonial empire - and now with a chance to reverse that) the first crack at New World settlement, represented by useful trading posts or claimed colonies.
12) The Islamic powers are not to be counted out in the colonization of the Americas either - most especially the Ottoman Empire, which has already aggrandized within the Islamic cultural community about as much as is practical and enjoys the theoretical ability to proselytize in the Amerind nations.
13) Oh, and Ethiopia is what it is because the Omanis have gone to great lengths to prop it up to prevent the Ottomans from cutting off their independent power in east Africa.
