but neither should countries like usa not build any infra excepting in their capital as that would be even worse and more than a little bonkers.
Firstly, I wish to clarify that I implied that only the USA should be the only country to only build infra just at its capital. While I mentioned that Tokyo is both capital and outlet, that does not imply that Japan should construct infra only in its capital. Therefore there is no such thing as "countries like usa" and it isn't fair that you take what I said and expand it into more. To clarify, I think all major countries should 1) build capital to 200 infra, 2) except for USA, build some infra for greater resources and increased IC, 3) some specific countries need 200 infra line to outlet. As regards Point 2, how much infra depends on resources needed, what trades will be lost during war, and what provinces are available to get the preferred double benefit of most increased resources with best increased concentration bonus.
In V1.08 the USA AI builds no infra. In v1.09 I understand that has been changed to ~80 serials of infra. Does that not seem like a huge change to make in a game that is supposed to be preparing the USA for fighting on 2 fronts come 1941?
Next, in last game as USA, I built 6 or 7 serials of infra in the highest IC provinces with consideration as to also high resources there. It taught me that all – except the serial in Washington to get a 200 infra capital for maximum upgrading AND a maximum outlet for best possible world-wide ESE - was a waste. All of the infra builds except at Washington was a waste because the only real useful benefit was the slightly higher IC due to concentration bonus. The greatly increased resources gotten from the other infra improvements were a waste because I was never able to trade my entire daily resource surplus off anyway. So I just stockpiled hundreds of thousands of energy, metal, rares and oils - even after thousands gifted to UK and SU. And all stockpiles that vastly exceed what can be used are a waste. Next, the little extra IC gotten because of concentration bonus was also fairly wasted, with a case for building a line of factories instead probably making more sense if the goal is "most increased IC." The USA does benefit from an early program of increasing total IC, so we don’t need to debate that again. But constructing infra in 3-4 IC provinces hardly increases total IC at all. And if USA AI is really building 80 infra serials, that must include many provinces with only 2 IC, and some with only 1 IC. That is simply building up economically a country's resources to a point not needed - so wasting a huge amount of IC.
But what is really worrying about Pang's alleged many infra constructions in USA and India with Set 33 or 34 is that it must cripple what the USA and UK AIs should be otherwise doing from start with available IC - which is build up their navies. Navies take years to build, need nearly no supplies to maintain for the long pre-war years while building them, can't be upgraded except for their brigades (which is minor except for CAGs) so they benefit the least by tech rushing, and are most efficiently build in long serials (meaning certain unit builds need starting in 1936).
But if the IC is not available at start because of too much infra construction, the navies will need to build faster later with laying down multiple serials - which is wasteful and also conflicts with trying to find later much spare IC then needed to later lay down multiple lines of army and airforce to avail of the huge benefits of tech rushing those units can get, which is mostly avoiding as many upgrades as possible.
WHAT ALSO BOTHERS ME IS THE INCORRECT FOCUS on how to make the AIs better for greater SP challenge. It is wrong to majorly change anything in this game when there are so many examples of smaller reasons why the game fails to deliver strong AI play. Instead, the many small things should be fixed. I'll discuss 1 example.
AI DOES NOT BUILD EXTRA ASW BRIGADES:
Experienced German player winning Battle of Atlantic against UK AI is fairly easy because the UK AI does not equip its original DD-1s and DD-2 with ASW brigade. In fact, I think it probably builds new DD-3 also with incorrect brigade. And maybe it simply never builds ASW brigades at all. While getting AIs to properly build brigades may be a considerable DEV challenge, all of Pang's concentration on major game changes certainly is not providing the best environment to achieve correcting serious faults already existing in the game.
Simply put, the intense focus to majorly change the game is wrong because it detracts from the focus to fix the many smaller issues that would definitely make AIs harder to play against.
Now, PB-DK, if you really think USA AI should have more infra except at Washington, please state where… and what is the actual benefit other than slight IC increase due to concentration bonus. I’m sure you agree that 10 IC for 2 serials of factories gives greater total IC than 10 IC for 5 serials of infra placed in the USA (and you can’t use Washington again because that serial is already taken).
Actually, if we look strategically at USA’s possible infra building then, on top of Washington, good candidates are San Diego, Pearl Harbour, and Wake for greater ESE in those places. This now lessens the need to run fleets to Washington for upgrading their brigades. Also aircraft stationed at Pearl and Wake will benefit very much as regards org regain. But over building infra with mostly getting more resources that can not be used is simply something the USA does not need.
EDIT: My major point is that "Pang is concentrating on the wrong thing by trying to improve the AIs via major economic changes." He should instead be figuring out how to overcome well known deficiencies with the AIs. I did edit here because I just thought of another example - the AIs preference to build very short serials - oftentimes only a single unit (but many parallel lines tying up huge amount of available IC). So, in v1.08 the USA at start has seven serials of CL-4. While the USA does need about 16 new CL-4s, that is most efficiently gotten by Dec/41 via one line done from start. These are the kind of "problems" AoD vanilla needs over coming for AIs to become more of a challenge playing human. Majorly changing the world's economy will not result in fixing anything that actually matters, IMO.
