You need attacked neutrals joining some side or some short of “dungeon master” player that moves the neutrals. A dummie neutral that can only defend is a new edition of that joke I call ACME wall :|
They are going to join some side or we would get neutral pieces … the other solution would be a victorious defending neutral would recieve magically its starting units after the attack. Also odd … the best and simpler solution is joining the whole neutral power to opposite side that attacked in first place
As for neutrals caring only for inner affairs, not true: you can take example on Spain, that was about to join axis in late 1940. Also South America, that probably will start neutral, needs some rule to join allies as they did in real world. Switzerland needs some monster defense or simply being impassable or we are going to have it invaded all the games as TripleA AI does :roll:
