I was reading about the Ha-60 engine. Apparently Kawasaki licensed the DB-601a from Germany. That engine was in a plane called the Bf-109 (aka Me-109) so it really should not have to be researched much. Then Kawasaki licensed it to Hitachi for naval use, as in the Judy. In 1944, the engines were using the same designation so in reality, shouldn't/couldn't changes be made so it was just one engine, whoever made it The same engine, no matter who made it, could then be used any any plane that required it. Just a little easier for the Japanese player.
But you have to research both engines. It would save the Japanese on research. Although, Hitachi did lower quality builds, the game is not to be a historical replay otherwise there would be a lot less cooperation between the IJA and the IJN.
Yes, even the Germans had problems with the engine. But why have two engines that were essentially identical that could have been used interchangeably except that one was used by a Navy plane? The HA-35 was used by the Navy and the Army and there weren't two separate engine sources nor nomenclatures.
There were about 30 different "Double Wasp" engines. Easy enough to say they were the same. Easy enough to say that the B-29, the P-47, the Corsair and the Hellcat all used the same engine. That would be incorrect.
The number of engine slots in the game is hard-coded, so adding more engine models would require code changes - but for what, turning AE into AEM - Advanced Engine Management? RangerJoe has a point, the Ha-32, Ha-33, Ha-35, Ha-43 and Ha-45 engines were all used in both Army and Navy planes, but are not "split" in the game, so why have a "split" for the Ha-60? Unifying the two Ha-60 variants will free an engine slot for an engine which is missing so far - the Ha-36 Mamoru which powered the first version of the B6N Jill (did that in my mod btw).
My pet peeve with the game are the PP costs for switching HQs of unrestricted units - it should cost 0 PPs to allow to maintain a proper chain of command.
