Just a general info post since the question has come up.
This game does have a full Map Editor, I just haven't released it yet. I am thinking I need to add the ability to handle one more set of hexside terrain and maybe one more set of in hex terrain. The Editor allows the scenario designer to create a wide range of terrain features. Things like their are three types of Woods (Light, Medium and Dense) each with their own terrain effects. There is also something I call "Active" terrain. Right now its just Cornfields. Cornfields have limited LOS effects (LOS must go through two cornfield hexes to be blocked). It is also destroyable. Fire and marching through them slowly destroy them. A lot of this you can't see because I haven't caught up on creating gif and jpeg files for the different types.
All this can be edited since they are just 200x200 pixel files. I realized I am no artist so I am leaving a lot of this do others to do a better job of. What I do do is give the Editor functions to allow the designer to change the transparency, image selection, and orientation (rotate the image for displaying).
The primary purpose of the CWE system is to allow anyone to design their own games or modified existing ones.
And, for those with some artistic talent which I don't have, to make it a lot prettier.
All the Units, Leaders, and Headquarters are created from data in XML formatted files. Once you figure out how to edit XML you can change a wide range of parameters associated with these.
The game itself works on the Orders/Threat based system. The player gives orders for actions like movement and fire, but the game executes them within the restrictions of observed Threats. If Threats become to large it will respond to the Threat rather than your orders. If you send a lone regiment toward a enemy brigade, the AI Colonel will "see" to overwhelming a threat as it approaches the enemy line. He will probably stop 100 to 200 yard out and start firing or even retreat instead of advancing. But if you send the same regiment forward with supporting regiments around him, he will not lose his nerve and will close with the enemy.
It is what I am mainly working on now to try to balance these different effects.
Also, adding more flexibility to the Order system so individual regiments can respond to direct orders even when in a Stance that doesn't support attacking.
