Ok, before going into any details, I am going to mention the fact that I have been involved in the last few months in two games of GD 1938. I have been playing Germany and Italy in one of them, and anyone following the AAR will know this. However I have also been playing a second game as The Soviet Union.
In each of them I went in with the following goal. Could the easiest victory condition (as I saw it) be achieved, by simply rushing the objectives, and declaring war as fast as possible.
Well: the results are in. I couldn´t.
In the first case, the German one, I came close. And I might still achieve it, but I don´t think so. The situation in the Soviet Union, is a stalemate, despite my best attempts to encircle, and push my way forward. So Thwarted by the soviets.
In the second case, the Italians, have almost achieved a victory too. But two pieces of the puzzle are missing. One is the all important island of Malta, which must be taken in all the victory conditions Italy gets to choose from. The second piece shall remain secret, just in case Malta falls, but this is unlikely, as there are now many spitfires there, and the British fleet has concentrated in the waters around it. I might gamble with a seaborne invasion, as the garrison there is weak, but, it won´t continue to be, i bet. So thwarted by the British.
In the third case, the Soviet one, the objective was simple. Get Rumania, Bulgaria, Turkey and Persia, while keeping the Soviet Union intact. Almost achieved, without firing a shot. There was a short war to begin with where I took half the Rumanian territory, from Germany, and then came to peace with them. Bulgaria and Turkey soon fell to diplomacy, and Persia was on the way to becoming Soviet too. But I had a discussion with the British player, and he flat out refused to let me occupy Persia without declaring war on me. I thought oh well, I will see if I can get the Germans to cede the rest of Rumania for continued peace, and he nearly did... but somewhere along the way, the British discovered what I was up to, and the peace talks I had with them, after taking half of Poland, with Germany, failed completely, and came to all out war. In my haste to get the half of Rumania I needed and to get Persia as well, I had to declare war on Germany (and Italy too). So I found myself in a war against 4 great powers... All wasn´t lost until I discovered that Britain had become a closer friend to Persia than the Soviet Union. Desperately I tried to get control of Persia, but, it soon became apparant that the Persians had other ideas, as they sided with the British. So Thwarted by the British yet again.
I guess this sort of proves you cannot bullrush your way to victory in GD 1938... although I would hardly call 26 turns or more a fast victory.
Both games are still in progress.
