This is going to look like I did waay too much work, but I had this map of 1066 Germany lying around from the idea I had for an AAR ages ago. The only small error is that Holland is part of the Duchy of Lower Lorraine at the start
Germany in 1066:
The Emperor is the Duke of
Franconia, and has 3 provinces, and 34 vassals.
The succession order is as follows:
Lower Lorraine - 2 provinces, 10 vassals (12)
Swabia - 3 provinces, 6 vassals (9)
Saxony - 5 provinces, 4 vassals (9)
Carinthia-Verona - 3 provinces, 5 vassals (8)
Bohemia - 4 provinces, 3 vassals (7)
Bavaria - 2 provinces, 5 vassals (7)
Upper Lorraine - 2 provinces, 4 vassals (6)
Provence - 1 province, 4 vassals (5)
Thuringia - 1 province, 2 vassals (3)
Brandenburg - 1 province, 2 vassals (3)
Austria - 2 provinces, 1 vassal (3)
Meissen - 1 province, 1 vassal (2)
Luxemburg - 1 province, 0 vassals (1)
Other duchies ineligible for election are:
Lombardia (elective duchy) - 2 provinces, 1 vassal (3)
Toscana (female ruler) - 5 provinces, 4 vassals (9)
Pisa (republic)
Genoa (republic)
Ferrara (archbishopric)
There are maybe a dozen duchies not yet in the game, so there will be more room for new players, or for the Emperor to be able to split up the larger duchies at his discretion.
If someone is playing Bohemia, Ves should create the title King of Bohemia before the AI does, or that player will be out of the succession order.
Someone could play Lomabardia or Toscana if Ves mods the startup slightly.
