The problem I find with supply is that its not really a problem and unrealistic.
For example you don't have fuel in HOI3 what you have is electric tanks that must be plugged into a grid, if you outpace the electricians you will have no power, if you strategically deploy to a province where the grid has been removed you have no power.
I believe that for supply to work and to become a really important part of the game play you need basically ports inland. That certain areas such as cities become essential cogs in the supply system, they should always be supplied and have the capability to build up supplies. One way of doing this is to have them behave like ports and have an ability to re- base armies to a city much like a fleet.
Cities, ports and airports should be major distribution points for all supplies. If I tried to imagine a simplified but realistic system I would see the capital as the main reservoir and supplies flowing out to fill up the regional reservoirs (based in ports, airports and urban centres)
It is from these Supply Dumps that units within range get supplied this rate of supply is modified by the infrastructure, you can push a unit beyond its supply range but increase the penalties until it can get no supplies whatsoever, winter could half the range of Supply dumps.
Of course you may then be able to make it more brutal and less forgiving for example if you quickly shift your armies from a victory in Poland to the French border you will simply not have enough supplies to attack immediately. You would need to re-base your armies to cities like Dresden or Cologne only then would supplies from the east start shifting to the west in large numbers. We must have already some system that can calculate the range of HQ so perhaps this could be adjusted to calculate a range for supply.
In the end I would like a supply system that was tougher and more realistic and became part of the game play its not really at the moment.
Now that I have done the hard work go off and make it so Paradox.![]()
good point.
in that case cities like stalingrade would get a real strategical relevance.
