I’ll assume the board won’t be changed; that’s a whole topic in itself.
Switzerland worth 4 IPCs.
RR as per latest post, but giving the CPs some more incentive to accept such as POWs or Moscow still counting as a victory objective.
Power up submarines.
Costs 3 IPCs to repair a battleship.
Limited number of new units in India each turn.
Turn order: G - R - A, the latter without the infuriating Serbian invasion.
Lose the French Biscay Battleship.
Add the Konigsberg (SZ26).
Give Austria a sub.
Allow tanks to be built turn 3.
More rational treatment of minor powers colonies - if you activate a Portuguese colony, France gets control; if you attack Spanish Morocco, ALL Spanish tts including Spain mobilize against you.
I’m experimenting with:
2 space movement for ALL units, subject to logical limits. If this doesn’t work, consider more general rail movement or the Munich factory.
Retreat and Pursuit rules for naval units.
Russian Civil War.
Promoting fighters that score a “kill” in air combat to “Aces” rolling @3.
Askaris.
