Diplo:
From my previous experience I did some trades myself. So I initiated early some trades with SOV about rares and some with USA. Also some about metall with some others(Eg. SWE). From then on the ai was handling that area again on its own and did build up a little surplus in all areas. Not that much, but it should be ok on the long run.
Also I influenced from the start now ROM/BUL/HUN for history reaons. JAP and ITA joined the faction as did HUN right in time.
All gameplay historcial, so Austria was taken "home" and Slowakia is now a puppet, rest taken into the Reich. I have some deeper event series around Munic events planned but not ready yet.
Memel was taken back as also MolRib treaty was signed and GER is mobilized and ready to attack POL.
Espionage:
Here I made a mistake in my first try too. I spend too much Leadership for Spying on too many countries. The AI is acting too good, so too many of my spies where dying etc..
This time I focused only on buffing/protecting my own country and the most important enemies now ENG and SOV. Both get mission counterspionage to help kill as most of their spies as possible as also to raise the threat of this two to have others not join them that easily or trade twith them.
In the picture you can see that ENG is building up its "home chain RADAR screen". So ENG took the decsion to build up RADAR in key provinces to be prepared for upcoming planes/ships, great..
Politics:
Here I did no big changes. You can see though that the Party Org is quite high due to the effort spend in the Espionage tab.
Otherwise I just picked up the next better law when possible. More Minister changes maybe when I'm deep in SOV..
Country is mobilized since July '39 and mobilizing was no big deal as the laws made the units already having 90% of men.
Also here I have plans for some more changes already fro a long time, but still not implemented. What is changed already is eg. that you wouldn't get more officers when switcing laws. The rate stays the same all the time, but also the specialist training exploit will be fixed in some to come version..
Production:
Here you can see the current build status now. Like ENG, I choosed the decsion to build RADAR in some key provinces to have a protection against planes(bombers) and invasions if I use the AI for my theatres. Second pic also shows 2 more single RADAR build. Thats because the ai builds RADAR on their own in high value provinces too if it has the money to do so. Because of that the USA can look quite funnily atm, as they may be able to build RADAR in many provinces..
Next to the lone DD that is in the queue you can see mostly land units. Some Mobile, GAR, INF and lots of Corps units that help to fill special need for AA/AT/ENG/ART as they incorporate the heavy stuff of that type or just many. Even the "Brandenburger" are being build(Comandos). After the first land build up phase wich should be finshed by now, the ai should switch to air force by decsion soon.
An overview over all produced units will be shown in the statistics..
Theatre:
I deleted the second command and thus put all units under one theatre command wich was taken by "von Rundstedt" who has Attack and Defense trait.
You can see that he is confident to push back the enemy on all fronts. Immediate needs are quite low.
We have quite some mobile forces to do some Blitzing and as you might see that there is no Mot-Inf icon, the Mot-Inf is incorporated in the Mech-Inf. As that units were to accompany the tanks. Normal Inf can be speed up by trucks via tech and thus made like the Mot-inf of the allies. The inital Mech-Inf in Treasure is also only equiped with trucks and Mechs have to be researched. So quite a good tradeoff to achive historical builds imho. Therefore the unit is named Mot/Mech in the Treasure.
We have some special units(2 Divsion each) of all areas already too, and some landing craft or Transport planes to use them all. Around 5 Infantry Divsions and ~30 GAR Divs next to some corps units should sum up for around 140 Divs. I'll look a the General later and post a pic if wanted.
Next to the two light Carriesr and two fleet carriers we have also a navy with two modern BC of Scharnhorst/Gneisenau and two BB with Bismarck/Tripitz! The initial 3 Superheavy Cruisers/Pocket BB of the Deutschland Class(have their own class in the Treasure Mod) and some new heavy Cruisers are also around as some LC and DD next to 5 flotillas of MTB(Speedboats) and 11 flotillas of submarines. As I didn't deleted any of the initial fleet that old BC are also around as the initial old SS/DD..
The Landing Craft Transports should also help in getting to Norway quick and also maybe help in the whole "Weserübung" campaign.
Because I focused this time on 2CVL/CV we have no Strat-Bombers by now, but that should change soon. Better to have the ships by now and have something to fight the RN as the other way around. But we have already quite some Fighters and 4 2Mot-hvy Fighters wich should be enough to hold of the Allies in the sky for a while. Also enough bombers to aid our ground forces for now.
Statistics:
Here yo can see the current count of units from our faction:
Japan has some more land units and ships by now.
But GER's navy is quite balanced imo.

ITA has also quite a big navy. Must add the carriers to the build ai though..
Air units are also good imo. JAP will later change to diffrent focus too. More about that when that happens.
Overall the ships take more fuel now, so a fleet in being can help saving fuel..
Sunk ships so far:

NatChi lost all its ships..
Technology:
I'll show that pics later, as we have 23 pics fro those alone..
This time I was more acting in that area to secure the carriers had up to date techs when I build them.
I'll show a pic here now that shows soem of the infra affecting technologies in the nation tab. You can see that these techs not only give a bonus, but also have some negative effects.
So you need to be carefull if you go down a route and not take into account the malus of a tech.

Overall it is desiged that way(should be) that you can go down a path for quite a time until it can be bad in other areas maybe. But as you see in the pic, you can counter the IC drop with the "overall IC tech" and the LS drop with an education tech. Thats the way it also works for range of planes etc..
