@Argothair:
Here’s an idea inspired by some of your thoughts: You win the game if and only if your team controls 2+ out of 3 “target cities” in both theaters simultaneously.
Allied Atlantic Target Cities are Paris, Rome, and Warsaw.
Allied Pacific Target Cities are Manila, Shanghai, and Singapore.
Axis Atlantic Target Cities are Cairo, Leningrad, and Stalingrad.
Axis Pacific Target Cities are Honolulu, Sydney, and Calcutta.
Here’s a (still only rough) concept for a variation on your idea. It’s aimed at accomplishing both of the goals that have been mentioned: on the one hand, encouraging the US and the UK to fight a multi-front global war, while on the other hand encouraging the European Axis powers of Germany and Italy to concentrate on their half of the map board and encouraging Japan to concentrate on its half of the map board. A lot of details are missing, so I can’t tell yet if it would actually work, but I’ll float the idea for whatever it’s worth.
First the background. If you look at a historical map of Axis territorial holdings in mid-1942 (the high point of the Axis conquests), you’ll see that the Axis powers, the Anglo-American / Commonwealth powers, and the Soviet Union were basically in three different geographic situations.
Germany and Italy in the European / Mediterranean region more or less held a single, large, contiguous block of territory running vertically from Norway to North Africa and horizontally from France to the western Soviet Union. Japan, similarly, held a single, large, contiguous block of territory (most of it ocean), with Manchuria in the north-west, the Dutch East Indies in the south-west, the western Aleutians in the north-east and the Gilberts in the south-east. Both the European Axis powers and Japan were therefore controlling a territory that had a single large perimeter, and they were fighting a multi-front war at various points along that perimeter; to oversimplify, they were each fighting on a circular front.
The US, the UK and the Commonwealth Dominions of Canada, South Africa, Australia and New Zealand, unlike the territorially concentrated Axis powers, were quite literally scattered over the map. Some of their territories were contiguous, but others (because of the presence of oceans and neutrals) were not contiguous; overall, their locations on the world map were characterized by dispersion rather than concentration. One important advantage of this dispersion was that they could reach (and thus reinforce) one another, whereas the two Axis blocks were more or less isolated from each other. While the Axis powers could visualize themselves as fighting to push outward to expand their respective blocks of territories, the Anglo-American / Commonwealth powers could visualize themselves as being outside those Axis blocks and fighting on multiple fronts to force those blocks inward.
The USSR, like the Axis powers, was defending a single block of contiguous territory, but unlike both the Axis powers and the Anglo-American / Commonwealth powers it spent most of WWII fighting a war on a single linear front rather than a single circular front (like Germany/Italy and Japan respectively) or on two circular fronts (like the US and the UK). The potential existed for the USSR to end up fighting a two-front war if Japan had invaded the eastern USSR, but that didn’t end up happening in real life.
As previously mentioned in this thread, in A&A the US tends to concentrate all its forces in one theatre or another (which is dull) and Japan tends to join Germany in a drive on Moscow (which is unrealistic) because the existing victory conditions encourage it. Argothair proposed solving the problem by requiring the Axis and the Allies to capture certain specific victory cities in both theatres in order to win. I’m thinking that it might be useful to refine this model by introducing the following distinctions:
The Allies (as a group) would have to control a certain number of VCs on the Europe map and a certain number of VCs on the Pacific map in order to win, but they would not be required to control any specific cities (which is a departure from Argothair’s model). In that sense, every VC on the Global map would be a potential target for any Allied power; it wouldn’t matter which one of the six Allied powers controlled such-and-such a city, though of course there are built-in limitations to what France and China can do in that regard.
The Axis, likewise, would have to control a certain number of VCs on the Europe map and a certain number of VCs on the Pacific map in order to win, and would not be required to control any specific cities. In this respect, they’d be just like the Allies. The difference would be that all the VCs on the Europe map would be designated as VCs for the European Axis powers alone (or alternately designated as primary VCs for the European Axis powers and secondary ones for Japan), and all the VCs on the Pacific map would be designated as VCs for Japan alone (or alternately designated as primary VCs for Japan and secondary ones for the European Axis powers).
Applying this is practice wouldn’t simply be matter of saying that, for example, Japan is prohibited from capturing Moscow, because that would just be another way of saying (in this particular case) that Japan can’t break the NAP with the USSR. Rather than saying that Japan is prohibited from capturing VCs on the Europe board and that Germany and Italy are prohibited from capturing VCs on the Pacific board, it might be better to make it more advantageous for Germany and Italy to capture VCs on the Europe board and more advantageous for Japan to capture VCs on the Pacific board. One possibility would be for VCs to have differentiated values depending on who captures them, wich is what I meant by primary and secondary VCs.
Just for illustrative purposes (these aren’t meant to be real numbers), let’s say that in order to win the Axis has to control 6 points’ worth of VCs on the Europe side plus control 6 points’ worth of VCs on the Pacific side. A Europe VC controlled by Germany or Italy would be worth 2 points. A Pacific VC controlled by Japan would be worth 2 points. A Europe VC controlled by Japan would be worth 1 point. A Pacific VC controlled by Germany or Italy would be worth 1 point. Under those conditions, it would be (for example) of greater advantage for the Axis side for Japan to go after Pacifc VCs than after Moscow.
There are probably other ways to achieve this kind of differentiation, but at the moment the above is the only one that came to mind, so I wanted to put it out for potential consideration.
