Just got my hands on the MOD and i have to say it is looking very promising. However theres one or two thing I have noticed/suggestions:-
(I appologise if any of these points have been made prior to this post).
Firstly. Spitfires and Hurricanes for GB. The SPITFIRE should be the more expensive and should out perform the Hurricane. The Hurricane was the mass produced backbone of the RAF for the majoirty of the war, with the Spitfire supplementing it. Just a simple observation, but if you want to go for reallity...
Second. GBs Golden Age. Should be triggered by a naval unit, not the Spitfire (as suggested). All though the Spitfire is a single symbolistic inbodyment of a nation's stand against tyranny, it was as a major naval power that she reigned. As a suggestion, the HMS Hood was the pride of the Nation at war's outbreak and was actually a very good warship untill the Germans came up with thier usual lucky streak and sunk it during the Bismark saga.
Thirdly. Although strictly speaking they were independent nations, the commonwealth countries could be placed under one Civ. Otherwise you may find Canada and Australia going at it. Although a possibilty, at the time of WW2, not very likely.
Fourth. Infantry. Everyone has been v.quick to come up with fancy tanks and aircraft ideas, no-one has mentioned the millions...and millions...of infantry that WON the war. U do not win conflicts with armour or air power. Its the men on the ground that secure it. To give a more realistic simulation, you could recreate several different infantry groups. Those used by the Americans/Chinese/USSR should be low cost and low maintainence. Germany, GB and the European powers should be more high cost. This hopefully would recreate the mass of infantry employed by the bigger countries. You could make European infantry slightly harder to force the AI to build more for the US et al. Besides, we all know that GB infantry are the best on the planet when put into a 1-on-1 situation
Fifth. UUs for GB/US (?). Spies. Although Civ3 already has espionage, its to cumbersome to mirror the true intelligence conflict that raged during the war. The SoE or MI6 could be another unique unit and act like primitive spies - trying to stir up resistence (insight revolt?), and carrying out acts of sabotage. Nations such as Japan and USSR should have no/less kinda units as they rellied more on straight forward military might. This was a huge part of the allied war effort and i feel that it would be lop-sided to create a WW2 scenerio without at least acknowledging this side of the war.
Thats my tupence...
