Nice work. The inset is well-handled and is easily followed. Too often insets can disrupt or confuse gameplay. Beginning in the north offers a slightly different opportunity, as there are more bonus areas but they tend to be a bit smaller than those in the other "corners" of the map. Players beginning in the Burgenland Kreis may have the slight advantage of greater initial isolation, but any imbalance resulting from that isolation is minimal and, in any event, quickly negated after about 4-5 turns.
Finally, thank you for including superbonuses for controlling each Kreis and Stadt Magdeburg itself. Players - note that these are defaulted to zero but can be increased to reward consolidation of territories.
