Those official code changes are unlikely to happen so what would be the best house ruled model you would recommend?PaxMondo wrote: Sun Aug 03, 2025 1:54 pmThis will only be "half-baked". Let me try though.
I don't see the issue with IJ and its RnD being the biggest issue. The biggest to me is that it can ramp up AC production far faster than realistically possible. If you look at US performance in this area during WWII, getting an aircraft into production once the design was complete (RnD complete) took months. In the game its instantaneous. Then, the ramp up first a big step up and then goes linear, in reality it is exponential with a SMALL exponent.
Right now, the way I rationalize the game to reality is by saying: RnD encompasses not only the Design of the plane, but also the production tooling and assembly line setup. Thus when RnD in game is complete this equates to production start in reality. OK.
So, to get this more aligned, the RnD repair factor in the code needs to be adjusted DOWN ... slow the RnD factory repair some more. How much? my best guess: about 25%. Decrease the probability of an RnD factory repair by about 25%, that will slow the development down significantly, bring it into reality far better.
Let's look at the IJ, the reality of IJ aircraft development.
The IJ had some fantastic aircraft developers. Jiro Horikoshi and Kiro Honsho are just 2 examples. World class. Put them up there with anyone. Willy Messerschmitt, Kurt Tank, R. J. Mitchell; sure; and Jiro and Hiro are right with them. So, they didn't lack designers. 1941, IJ still cannot build a 2 stage induction system. The game allows the Ki-49 Helen to be built in the game in unlimited numbers, it is far and away the best IJA bomber. Why was Ki-21 Sally built until war end and in 10x volume? The Ha-34 engine in the Helen required a 2 stage induction system that rarely ever worked. They blew up. Without it, the Helen could barely take-off, it was what is known as a "hangar queen". Ki-94? Great looking plane never getting into production because 2 stage induction couldn't be done. A7M? first flight was in early (March?) 1942. Flew great, except grossly underpowered because the engine was still a single stage, multi-speed blower that couldn't deliver. Didn't see one in the war until 1945 when the 2 stage blowers were finally starting to be working some of the time.
Now, the why of the 2 stage induction is a VERY long story. Moot, because it happened. What is relevant is that it caused the developers to "waste" all of their time working on projects with little (very small) incremental improvement. Let's use the A6M as the exemplar. The A6M in all of its version remains a 350mph plane. Period. Whether built in 1939 or 1944, it is still a 350 mph plane, which by early 1943 was too slow. Some players get all worked up about facing the A6M8 in 1942. I don't see why or how. Sandbox it. P39 .vs. any version of the A6M. Equivalent pilots. They are a match. Is the A6M8 better than the A6M2? Sure, marginally. In the sandbox, maybe 15% more pilots survive, maybe 5% more wins. Still basically a 50-50 fight. The P-39 ruggedness and armament negates the A6M MVR. Forget the date that the plane appeared in the war, it is a 1939 design. It is a plane that both the P39 and P40 are well able to compete against. Neither of those planes were used in Europe for a good reason: they were not competitive against the Me and FW designs. They were flown in the Pacific because they were competitive against the A6M and the Oscar. It was the Frank that caused them a lot of issue, but that wasn't until 1944.
In other words, the devs got it right in my mind. Advancing the A6M family; just a little sauce for the IJ players. Little impact on the allied player.
So, to summarize. Major issue is the ability to move from RnD right to HUGE production. Without a major re-write of the code, the best fix is simply to decrease the repair probability of an individual RnD factory. My best guess is about a 25% decrease (yes, that is a LOT). The intent would be that the IJ could still advance a plane, but it would take "National Will" (think the Man to the Moon project of the 60's or the Manhattan Project), and then only allow for ONE model to get advanced IF you chose to put all of your RnD on it. Yeah, it would basically remove the RnD aspect from the game entirely, but it is unbalanced the way it is. I would also suggest that if this done, that the variable be exported to the .ini file so that modders could use it.
Would 3 factories + engine bonus start slowing the ramp-up enough?
