What KristiB says about the factories,etc. sounds reasonable. Only Major cities, but that should be easy enough to figure out. Oh, and Kristi; try sitting on their food tiles until they are below size 6 and then send in those Argentine bombers.

That should help a lot. Don't worry about the defense factor either,the RNG is your friend. I have seen my BBs take entirely too much damage from silly DD units.

That was back when their defense was 5 no less!
Japan update,Week 43,1939- On their turn, the US fulfills my prophecy and runs onto that stack of Soviet subs near the Kuriles,thereby declaring war. The 12 CA mysteriously vanish, while the 6 BB units proceed to spend the next 7 weeks so far beating on the Kuriles. I find out just how vulnerable ships in ports are to shore bombard.

Quite a few precious DDs lost! USSR finished off Turkey this turn;they took all cites except Ankara, which they razed.
Week 44- My SNLF seize Fakfak, and we notice Sarmi is unprotected??? Starting this turn about 50+ US DDs proceed to head SW down our coast. By week 50 they are reinforced by about 10 CL + 10 more DDs,and 15+ subs. Huge naval battles erupt of course. They are currently in Sea of Japan!
Week 45- I have that 2BB+2CV group east of Tokyo;they take out 3 DD and a TR heading towards Tokyo. That was the first TR I've seen; if they had used those stacks of DD and CL to escort it it would have made it for sure. I capture Sarmi after shore bombard cripples the brand new defender!
Week 46- Djibouti razed! La Coruna taken by France.
Week 49- Paris finally falls!
Week 50- We take Davao. I had other plans but the US based like four bombers and a fighter there and started pounding the Carolines and menacing my shipping, I lost some more navy to those bomb raids. The US air units are destroyed by shore bombardment! Air + navy units seem to take damage first from bombardments and bombing, that I didn't know.
Bye this point, other then the dozen or so US DDs in the Sea of Japan and I think those BBs wasting their time shelling the Kuriles every turn only two small stacks of UK DDs near Hainan are visible; I have cleared the seas east and south otherwise. Some US ships slipped away damaged but more died. it was very costly though! The Southern cities are coming on line,and the $ I got trading an Oil and a Fruit have kept my economy going. The Italians surprise me by showing up with 2 SS near Borneo to pick up their fruit the turn that I make the deal.

I barely have enough to keep a positive income now. I am running 70% science and making a bee-line towards Zeros. Why anyone would ever build Georges after you get Zeros much earlier and they are better is beyond me, you might want to take a look at those two Rocoteh.
I have Foo Chow surrounded and three artillery seiging it, but the Chinese have at least 3 HMG there.

I am gathering a shore bombard group to come help squeeze them now that the Home Islands are safe for now. Those 3 US CV groups just keep sitting NE of Wake and raiding every turn. Very annoying actually, but I have shot down quite a few of them with Flak. On the down side, I am seeing Chinese Marines now,and they have finally started building fighters. C.China has gone dead quiet after their surge of Armor, I think they blew all their money on them maybe.
Naval losses to date:
US- 84 DD, 36 SS, 13 CL/CLAA, 1 CA, 1 TR, 1 CV
UK- 14 DD, 7 SS, 9 CL, 4 CA, 1 CV
NE/FR- 7 DD, 17 SS, 2 CL, 1 CDS
IJN- 12 DD, 19 SS, 11 CL, 3 CA, 1 TR
I've been very careful with my BB/CVs as you can see. The US is carrying the war in the Pacific, but a few UK units are showing up. I have the US backed off a line roughly from the Kuriles to SE of Wake Island. Scouting is a must!
