I just used the J1 attack for the first time and it turned out pretty good. Japan was going to take India and then Germany had Russia at the start of the next round (played by someone else). It was a nice effort on both our parts to keep our eyes on the prize and not be deterred by the Allies threats.
Russia was forced to try alternate strats and purchases some sea units incl. transports to drop some units into Germany. Obviously a mistake as that money could have went to defend Russia. However, it would have only been a matter of time before Russia fell anyway. A major IC build by Germany (on G2) really helps with a quick push. Does anyone else do that with Germany?
Also, the Americans made a big mistake by leaving sea units (incl. three loaded transports) two spaces off the coast of France. He thought he would be able to reinforce with UK units which he did. But instead of bringing ALL his UK units he used two Cruisers to do an amphibious on Norway. He missed on his pot shots and the Norway attack was a big failure. I don’t think he expected the Germans to come after the US stuff either now that it was reinforced with UK as Germany would have had to sac their planes by taking two hits on the carrier. That battle went all Germany’s way with the carrier and both planes surviving. If the UK had of reinforced the entire fleet with both Cruisers as well it may have been a different outcome. Anyway, because of that mistake Germany had no immediate threat of a US landing in Normandy and was able to take an extra couple rounds for the Russia push.
On the Pacific side it played out very well for the Japanese. With the mistake of overlooking an Anzac Cruiser that took out a Japanese destroyer blocker so the US could destroy three transports being the only real mistake by the Japanese the push into India was quite easy if only delayed by a couple rounds.
Allies condeded!
I think I like the J1 attack and will try it again in my next game.
