I have never played with victory cities. The game is always called well before that and someone surrenders. There could have been a time when it was temporarily met but no one would have even noticed. Either the allies would surrender just before or just after. Once the game becomes obvious as to a clear winner, agreements are always made to play a certain number of turns with some qualifiers that must be met, otherwise the losing side must surrender.
When I was in the army, I remember just one playing the Axis IPC victory if anyone remembers that. The axis for a moment, that could not be maintained, had the level of combined IPC’s to win the game. I was on the allies side. 5 of us were playing. The axis claimed their victory and we, (the allies) were livid and declared it a false victory.
I understand you issue with Japan in the sense that it is Germany who will always dominate when the Axis wins. But that does not take away from the importance of Japan. If Japan is able to win in the Pacific, (without declaring an end to the game), it can then place incredible pressure on Russia, the UK via Africa, or the US via Alaska or Hawaii, that will bring victory to the Axis.
Japan would be a power house if allowed to take China, India, the Middle east, and all the Pacific Islands so they cannot be ignored. They just need to be slowed down. One of the things I think should change to encourage action in the Pacific without unrealistic NO’s and “technical wins” would be dramatically lowering the costs of building a Navy. Subs $4, Destroyers $6, Cruisers $8, Air Craft Carriers $10, Planes $8, Tac Bombers $10. Then you could have real action in the pacific without taking away so many resources from other fronts that are more important.
Also, instead of making Hawaii worth more to the Japanese then to the Americans, which makes no sense at all, they should be penalties to the losing country, such as a one time surrender of IPC’s, $20 or so to mimic a loss of morale, as suppose to a constant unrealistic stream of income to the Japs. These things combined would be more realistic, historical, encourage action in the Pacific and still allow for the efficient expenditures of resources.
Historically, the US spend less than 15% of its resources fighting the Japanese in the real war. There was a reason for that, but there was still meaningful Pacific action. That was because building one air craft carrier with a full complement of planes and a ship or two did not require nearly 100% of their resources for 3 months.
