WHOA ! THANKS for letting me know.
Unfortunately we don't have a UK or USA player, the last guy wanted to play Republican Spain. Don't ask me why! Anyway I'm not that great at all this management without a pause button but the Japan and Spain players are worse. I don't think I'll get much help from Japan, he's having problems with defeating NATCHI. He started the attack with 22 Divisions, which was fine but he had no INF in his production que and as the lines got wider he had no divs to fill the gaps and had to fall back to Shanxi, throwing his plan of NATCHI puppet behind by a year or 9 months at least. He also did not use any of his puppet INF, nor did he redeploy ALL of his island garrisons, though he did redploy them eventually on advice, it was too late.
He's now (in 39) launced another offensive after building 80 INF He should succeed this time. There is a house rule that you can only ally with nations of the same goverment type or at least similar ideology, USSR allied with COMCHI which means that USSR will DoW NATCHI and attempt to hinder the JAP movement there. he may also DoW Japan. IIRC there is an event which forces COMHI to attack NATCHI ? Hence JAP is almost certainly doomed unless he gets his act together, the game will be very disappointng for him. I did have a look at the save game (with the USSR player) and his que is kind of horrifying with like 30 ships, 20 INF divs etc. Should be a good challenge.
I have to say that MP is really very intense and definetly worth a try if you have a dedicated, committed, responsible group.
