I'm waiting for Di:G to be made compatible with FTM before I play Germany again, so I decided to try a game as Japan, which I don't think I have done since before SF came out. The game runs a lot faster and I actually wish I had an even slower setting for when fighting.

I do think I must be missing a lot of events going on around the world, my event box defaulted to show NOTHING at start up, which is odd. I need to go check the settings for all the messages.
I really like the events for creating/expanding the Japanese puppet after you take part of Shanxi.
The Japanese OOB is a mess and I spent a lot of time trying to clean that up. I swear they seem to have less decent leaders than before (HoI 2).
In order to save supplies I always bring home all the island garrisons. After manually turning off most of the supply convoys to the islands, I let the AI take control of the supply convoys again after a day and it immediately started those convoys again, even though those troops were long gone. It's been a strain on my supply system for the invasion of China. Very annoying and not sure why they would continue to supply empty islands.
The Germans invited me into the Axis in '37.
I've done a lot of trading in this game and early on it was hard to keep my numbers in the green. I sell a lot of supplies to other countries and my main trading partner is the US.
My TAC units never really go below 99/98 even though I use them all the time. In Europe you always need to reinforce them after the damage they take there from ground units/AA.
As someone mentioned before, they are seeing the supply of their units more at 75% most of the time rather than 100%. I see more of that in China but it varies. Nice to see that though. Before it seemed to be all or nothing for supplies.
The invasion of China started in July of '37 and it's the middle of September now with Shanxi & Communist China gone and about 2/7ths of Nat China under Japanese control. In the south near the coastline my 4 division Cavalry army basically walked through all the way to border (along the coast) and to Nanchang. Never had any resistance until I got to there. Resistance is starting to stiffen in a north/south line but with the communists gone my troops in the north are facing disorganized militia.
I'm curious to see what game events occur for the other Chinese states.
