I used to play a game called Civil War Generals 2. In this game, there was a scenario creator option. One could place the military units, leaders, goals, etcetera on the map. Basically create everything and set up the campaign. That would be great if someday a patch could be created to add an editor to this game. That way, if someone wanted to create some of Napoleon's earlier campaigns, or early revolutionary campaigns, or a fictional one, it would be possible.
Just an idea.
