I think that if Germany falls, Japan still has a shot at winning. In one game I played, Japan had already taken Russia and was pushing into Ukraine and Kerelia. However, Germany surrendered to the Allies on the very next turn so it was USA/UK vs. Japan. If I remember the calculations correctly Japan was making around 69 IPCs a turn with UK and USA at 77. For about 50+ turns, trench warefare waged across Finland, Eastern Europe, and East Africa with Naval and Aerial battles raging across the English Channel. My God it was great!
