Just some thoughts whilst im ripping off the poor at work,i used to play a game called combat mission (i know Conq did too).Sort of similar to ntw in the fact that you fought a battle with a time limit over 1 map.
Although i do remember it being modded for campaign use where you made several maps with one following on form the next.So the first map was limited to 1 hours gameplay on a smaller then normal map(so easier to create) where you had a position or area to take.
If you got this position then you moved onto the next map in the "series" until finally you hit the last campaign deciding map.Now aswell as linked maps the forces you used were adjusted for the next map according to casualties and each unit had its specific "unit name" making it more historical thus more engrossing in the campaign.
This could in theory be played "command style" with a setup time agreed at the beginning to sort out the armies layout say 10 mins,then the battle could commence.
Now i dont even know if this is possible with ntw,but i do know it would be fantastic to play out.
You could in theory play a real time waterloo or borodino.
Thoughts gentleman??
