well maybe this thread will fill up with 1st moves for most of the maps!
Ofcourse I played the WWIIClassic map and board game of it so I guess I will give my strategy for that one and goodluck collecting and documenting all the 1st moves!
WWIIClassic map: Allies - the 1st moves for the Allies is usually have Russia buy mostly Infantry and 1 Tank and push back Japan as much you can but concentrate on Karelia and holding it and then pressure Germany through Eastern Europe while your ally United Kingdom builds a Navy and gets into Western Europe together with your ally the United States who is sending Infantry on Transports to Western Europe and so basically if the United Kingdom can hold its Navy and Transports then eventually the 3 Allies can squeeze Germany and take its capitol first and then team up and take down Japan's capitol
Axis - the 1st move for Germany usually dictates the rest of the match vs the Allies. Germany tries to assault and take Karelia with as much as it can (save something to take out some of the United Kingdom's Navy) except for a Transport and Battleship to help start the takeover of Africa. As Japan most people do the "Pearl Harbor attack" to start which I do (use a couple Fighters and most of your Navy) and then you want to build a Factory quick and start marching as many Tanks and Bombers you can to go across Asia and assault Russia and if Germany can hold off the 3 Allied countries before Japan takes Russia's capitol then the Axis should be able to take down the Allies
