Ok friend.  I thought I would get serious about my long time gaming hobby, and try to actually write a game.  I was somewhat inspired to do this by the release of Unity of Command, http://unityofcommand.net/   It's an ok game, and boils things down to a very simple level.  It lacks a lot of details I want in a game however.  The turn system is I go, you go.  So there is a lot of issues when the first player gets to make multiple attacks and the defender just sits and waits.  

Years ago I played a DOS game call V for Victory (later renamed World at War) . http://www.ibiblio.org/GameBytes/issue21/greviews/crusader.html  They were great games with a we go (turns from both sides plotted and then executed simultaneously.   Another thing that i don't think has ever been done in a wargame is having multi player in a game (that is supported by the game) .  So my game will be call Corps Commander, with each player commanding a Corps.  Units will be Battalions and Regiments/Brigades, so each Division will be 4-6 units (the standard infantry division is 3 infantry reg. 1 art reg, 1 recon bn. and others assigned from the Army)  Most Corps are 2-6 Divisions, so it i can pick good battles players will have 15 to 20 units to move around.  I think that would be the limit of something that is intended to be a fast paced game.

Right now I am working on a mock up of the User Interface in C# (and trying to learn C#), writing the units code (what goes into making up a unit) looking for a good generic first battle to simulate. (it will probably be fictitious)

What I am planning to include for now are:

1. An Army Commander that can move and reassign units to Corps Commanders.
2. Corps Commanders that can control only the units assigned to them.
3. Aircraft and Artillery Assets at Army level.
4. Hospitals and Supply depots that will effect how units are supplied and replace wounded soldiers
5. Unit stats that include Experience, Supply, Leadership, Disruption.
6. Different levels of unit orders, ie all out assault, attack, all out defense, mobile defense, probe, withdrawal.
