Great idea!
A friend and I talked about lines of supply and how it should be added to Civ. You basically got the gist of what we where thinking. We covered several things that you dont have in your proposal.
One thing we talked about is a city upgrade. We came up with the Supply Depot and it can only be built in cities with Granaries. The Depot increases the cities supply radius and is need to create the supply unit.
Each age had at least one basic unit (Caravan, Supply Wagon and Supply Truck) and some special supply unit could be made if you researched the right tech. For example:
- Cargo Plane could drop supplies to a stack to supply them for one turn.
- Blockade Runner is a navel vessel that could supply land units near a cost
- Smuggler is a land unit that could reduce an enemys supply unit radius and have a limited supply radius for friendly units.
You can track which units are out of supply by dynamically giving them a promotion called out of supply that way you can track each units supply status.
My friend and I also talked about adding more structure to stacks. We kinda modified the idea Civ III concept of the army. This unit could hold other units and make them into one supper unit with some strength bonuses. The differences from Civ III army unit are that units could be moved in/out of it and the unit gains the promotions of those in the stack (The effectiveness of the promotions would be divided by the units in the stack). Think a transport that takes the properties of the units in it. These units would be Company (Two units), Battalion (Three Units), Brigade (Four units) and Division (Five Units). These units would be available after Military Tradition is researched.
