In addition to correcting the Poland/Prussia border note that the Greece/Bulgaria border should be different with Bulgaria having an Aegean coastline.
Divide “Karelia” tt with a new “St Petersburg” tt in the South with only a Baltic coastline. Karelia retains the Arctic port.
Switzerland worth 3 and a bigger army.
I give every power a starting fighter in the capital with G & F having an extra fighter in Munich and Lorraine respectively. In addition, fighters built on subsequent turns increase hit roll +1. Starting fighters have no combat value, those built on round one fight at “1” and so forth up to max 4. Just mark each fighter’s strength on the wings. Maximum 2 rounds for air combat, still the higher number of surviving aircraft that decides air superiority. Only the excess may strafe.
SZ 18 enlarged to encompass whole Albanian coast.
Belgian Congo loses coastline and become a “jungle” tt; units attacking it have -1 modifier and cannot apply artillery bonus.
To give CPs more of a chance:
1. Lorraine extended south to border Marseilles; Paris moved to where “Burgundy” is now.
2. Rome extended to have a SZ 18 coastline.
3. Maximum 4 units built in India per turn.
Would anyone ever build units in Canada?
I’m not convinced about UK starting neutral. France only mobilised under the certainty that Britain would join it; Belgium was merely a pretext for Britain to go to war.
Finally, to make the game playable, replace the combat units with colour coded chips, all but the “topping” infantry piece.
