No, I was very unfortunate.
I did not use Yogo for an IC and didn’t concentrate on Africa at all (with Germany). However Italy only concentrated on Africa and was really succesful there, building an IC in Egypt and drove the Brits south all the way to their (by then) heavily guarded IC.
I DoW on G4 and concentrated on Leningrad. I conquered Vyborg, Karelia and Baltics with massive armies. I had 3 trannies and an IC in Norway, so my northern army attacking from Finland was huge. Russia kicked the hell out of my Baltic army, but couldn’t touch the others and with help from my trannies and SB I took Leningrad. I also killed the SU army which attacked my Baltic army, because there was most of his offensive capacity (tanks and art).
In the mean time I kept the Brits busy with subs and bombers. They had to invest at least 12 IPC every turn for Africa and the three trannies from G1 made sure their first turn was spend on inf, so their fleet never became massive, because of my swarms of subs circling Britain and cutting off convoys.
I must admit I played it against an inexperienced opponent, but his extremely lucky dice rolls did make it a very difficult game to win. My invasion of Leningrad saw about 12 defensive hits out of 14, IIRC.
