My play group has just recently, which resulted in a land-slide victory for the Central powers, and the discovery of some rule flaws. Rules changed:
Romania and Arabia now have different mobilisation objectives. (by Flashmans request)
Italy and USA now have much more static entrances.
Colonial mobilisation has been limited. (Can only mobilise units equal to IPC value of that territory)
Portugal can now be a colony.
Neutral Greece’s entry is now more historic.
Persia no longer has rail-roads. (Flashman)
Given the British dominion a transport capacity of 3. (simple error)
Colonies can only mobilise convoys under the same owner as the territory.
ALL neutrals (including aliened) are now full neutrals. (they can only be mobilised at certain points in the game)
Serbia now has 5 Infantry.
Made it so powers don�t start with ‘convoys’. (Simple error)
Railed in units now attack @ full strength. (players found it more fun this way)
Feel free to suggest rule changes.
