I wrote up my thoughts on Shadow Empires logistics here.
I completely concur with PodCats summary of the problem with logistics in HOI IV, you can ignore it until it becomes a problem. (Although to be fair, I learned to increase the infrastructure in eastern Poland before invading Russian) and once it becomes a problem its really hard to fix.
I have two concerns, first the AI issue. But second the fun and micromanagment issue. I found that both Le Resistance and the Man Guns, added more stuff to do, but it didn’t make the game any more enjoyable. They both really interrupted the flow of the game for me, especially when I was in the middle of invading Russia.
