My thoughts will probably stay at opinions and theories, unfortunately. I don’t play “Deluxe” face to face. I play online, and usually the Balanced Mod. For face to face games, we usually stick to Anniversary Edition as it is a great game, and more manageable in one sitting.
Staying on the production facilities subject, I agree with you that they sound fun and interesting, but I agree with your group that it might be too much to implement on a regular basis. They would change the game in a huge way! Might be better, true, but a huge change is hard to get universally accepted.
The shared, and noble, ideas behind Balanced Mod and your house rules, are: minimize the need for a bid due to imbalance, and expand quality strategic options in different theatres of the war. Sealion, Africa, Mediterranean, Pacific Islands, etc.
It seems to me, putting a major factory in Novgorod, and a Military Depot in the Philippines, both strike me as limiting the variety of choices the Axis have. Germany is punished for not going Barbarossa, and Japan is punished for no J1 DOW. Neat ideas, but the resulting effects on game play may take away from your larger intended goals.
Just looking at the prices, they seem expensive. The minor has no increased value from OOB, is now more expensive, able to be hit by tac bombers, and is limited in production unit type. What are your thoughts about 8, 12, and 16(or 18) pricing?
Japan purchases more factories than any other nation, and I would love to see how far they could extend their power into Asia with some military depots in Chinese and Russian territories! :-D
