Mmm... what scale operational do you reckon it could get down to? Like, could it handle the 1809 Danube valley campaign?
As I understand from the forum discussions, there are global scenarios and scenarios covering only one battle. So it seems the editors (map and scenario) of the game are very flexible.
You can have a look at Matrix Games. Here are some features:
Random map and scenario generator with optional shroud of darkness and mirror map functionality, infinitely replayable!
A Wargame Construction Kit-like editor allowing you to make any wargame scenario you like
Realistic Supply System that can be harassed by damaging bridges and ports or by interdicting enemy supply lanes with your navy or airpower.
Customizable Chain of Command
Excellent PBEM cheat prevention mechanism, not even re-installing the game will let you cheat.
Detailed, but fully automated mini battles, with results that show you what's happening during the battle.
Engineers can construct roads and fortifications, blow bridges and build airfields.
Excellent Fog of War, depending on your recon level you have full information, partial information or almost no information on enemy units and hexes.
You can control what all your towns and cities produce
Up to 4 research levels for almost all equipment; possible to upgrade existing equipment both in service and on production lines
Fictional USA and Europe map scenarios, as well as a Diplomacy style scenario and loads more (see the full list in the More Info section)History Screen in which you can review all moves the enemy made in his turn
Not just limited to 2 players, scenario for up to 9 players are included
Very customizable units; you decide the weapon mix of your divisions!
Command forces on land, sea and in the air
As I said I don't own the game, so I don't know how good this game handles napoleonic campaigns.
