UK Double IC

Sweet!  Thanks guys so much.

Yes, I have tried. It doesn’t work. With only 1 IPC, you can’t produce enough units to get your money’s worth out of it.

It seems to be a popular view that Japan is wasting its money if it buys a complex before it has maxed out the first one (i.e. is transporting 8 units/turn to the mainland).  However, I am of the opinion that 2 tran 1 IC–this is assuming $1 bid to Japan–is the optimal J1 purchase for getting units to the mainland quickly.  There was an old thread (sorry, I couldn’t find the link on my first search and I’m too lazy to look harder) that had some calculations to this effect, but for the short version, consider:
—If you build 3 tran on J1, you can put 8 units in Asia on your second turn.  However, with 2 tran 1 IC you can get 9 units there: 6 from your three transports, and three more from your complex.  With a 2 IC purchase it’s down to 8 again, one from your transport and 6 from your complexes.  (I’m assuming throughout that the UK killed your transport in SZ 59 so that you only have one to start with.)  So if you’re trying to get as many units to Asia on J2 as you can, 2 tran 1 IC is the way to go. 
—4 tran on J1, using a bid of $2, is also a good way to start fast.  However, in this case your capacity outstrips your income; it will be a couple rounds before you can actually get new units fast enough to keep your transports busy.  The 2 tran 1 IC buy is better optimized at keeping your production/transport capacity matched up with the number of units you can afford to produce.  In particular, a 4 tran J1 purchase enables you to put as many as 10 units into Asia on J2 if you clean out Philippines, East Indies, Okinawa, and Wake, but then you run out of island units and can only make up to 8 new ones in Japan.  So you get a lot of inf on J2 but it’s more of an anomaly, where the 2 tran 1 IC buy gives you a smoother and more continuous startup.
—As far as location, I like FIC the best.  Kwang is farther from Moscow than either Fic or Man, so if you’re trying to put pressure on the Russians quickly you want either Fic or Man.  You can supply plenty of troops to the northern area from Japan itself, so the complex is needed more on the southern end.  Plus it enables you to get to Africa, Caucasus, etc better.
—So far I’ve been assuming KGF.  In KJF you should certainly be a bit more hesitant about getting factories up quickly.  However, I’ve found that a FIC complex, which is always where I build on J1 if I build a factory at all, can be very helpful in KJF.  Ideally when defending against an American fleet you want to defend as far out as possible, e.g. with a fleet in the Caroline or even Solomon islands.  However, if you’re forced to fall back, FIC is a great fallback point.  The key thing about it is that it borders all three of your valuable islands.  If you get in trouble you can fall back to SZ 36 and build more ships there to join your retreating fleet.  Often this will be enough to prevent the Americans from taking any of those expensive islands right away.  If your only factory is in Japan you’re forced to keep your navy farther north to incorporate the new builds, and the Americans have an easier time getting to the southern islands.

Honestly, it would have to depend on what England did.  If they took Borneo and New Guinea, sunk the Submarine in SZ 45 and sunk the Transport in SZ 59 then Japan would be in a REALLY bad place on Japan 1.

If all they did was move into position, then I would eliminate China (to get the fighter) and then plan to make a massive dump in FIC on Japan 2 (with a complex on Japan 2) to try and get India.  It’s the most secure victory you’d have probably.  Either way, if you force the allies to dedicate their firepower there, you MIGHT be able to get Russia weak enough that Germany can tank dash (as in 8-12 tanks a round) into Russia

japanesse IC in brazikl i8s devestating, US ic in Norway is evil

Actually did buy ic´s for japan in folowing places in one game (i won)

IC: Fic, manchuria, sinkiang, kwangtung, china.

I agree, the game is already favoring the Allies. A great bid for the Germans then seems fair to me.

I’ll build two Japanese Industrials on the Mainland in one of two situations:

Most Likely - I expect a Kill Japan First allied strategy.  Either because of National Advantages selected, or because of previous experience with the person or because of how Russia and England developed their turns or all of the above.  In this case, I cannot expect to have transports and surface ships available for moving units from Mainland China to the Asian sea board, so the complexes are worth their weight in gold.

Least Likely - I plan to engage in a Kill America first strategy.  Again, I won’t have transports and surface ships to protect them for long, so I’ll need the complexes eventually.

I disagree.  Russia will not fall at all if Japan is at the gates of Moscow because Germany will be at the gates of Berlin.

Actually, the BEST game I ever had was when England went balls to the walls against Japan by landing in Archangelsk, through Russia and into Novosibirsk while Russia pushed into Europe and America worked on Africa and landing in S. Europe (as defined as W. Europe, S. Europe, Balkans and Ukraine.)

This maximized Russia’s income because England liberated land while Russia conquered land and it conserved Russian armies by not forcing Russia to trade with Japan.  This allowed me to get 30 Armor with Russia, and if Russia is strong enough to have 30 armor to throw back and forth across the board with impunity (or very near) then it’s game over for the Axis.
