Quick Testrun with new version until May 1941
Ok, another quick testrun with the new version until May, 1941. My observations :

- Japanese conquest of China was finished only in mid-1941. I think this is better. Though i dont know if it was specific to this run. Usually it ends in 1940 latest.

- Italian AI is making landings in Norway which it should not do.

- Italian AI is again overrun in North Africa within 2 months. It sent few divisions to Greek border but again was overrun within a week or so.


The root cause is same in both situations. British AI assigns many fleets to "convoy raiding" missions and cut supplies everywhere. Italian AI couldn't send supplies to Albania, so it cannot send more than few divisions there. ( Interestingly, AI was trying to send supplies to Albania through Napoli, instead of through much closer Taranto ).

AI Italy heavily use "convoy escort" missions but its navy is simply too weak. I think the imbalance is caused by Italian AI's almost total lack of naval bomber use. In 1940, it still had 72 naval bombers ( the same number they start with ). They didn't even use those continuosly. On the other hand, they had around 1200 fighters. I think some kind of balance here ( and telling AI to conduct "naval strike" missions in the Adriatic and Central Med ) could save the situation. I am sure 300 naval bombers + 200 tactical bombers on the naval strike mission in Central Med would dramatically improve the supply situation.


Using naval bombers to scare off British raiders is the only viable tactic for human players too. AI should follow the same tactic. Otherwise, it will lose its navy real fast.

I think Italian Army is too big compared to the scope its land theatres. Shifting some amount of MICs to plane production seems like a good idea to me.

- Yugoslavia picks "Crush the Ustasa" in the historical option. In Vanilla, it chooses setting up Croatia instead. While i agree that "Crush the Ustasa" is actually the historical option, it ends up with non-historical outcome. I suggest reverting to Vanilla path :

+ Yugoslavia picks setting up Croatia in 1940.
+ Germany should avoid "Demand Slovenia" in historical mode. Or it should take it only if human Yugoslavia follows Allied Path.
+ Yugoslavia should follow Axis road with "Invite German advisors" and "Join the Axis"
+ Yugoslav coup now will switch Croatia to the Axis side and provide the German AI with a conquer focus.
+ Then German AI can declare war on Yugoslavia whenever it wishes with Croatia on its side.

I think this historical route prepared by Paradox is more suitable than the current one. It makes it possible to have historical Croatia.
