Sounds like Nord is getting back-in.
“After taking a few years off, we are back looking at the games and what can be done to make them better. The games will no longer be for sale for the 'hopefully' short term. NSD has parted ways with Slitherine and thanks them for the many years of support.”

I never cared for any RTS style WGs until Take-Command and the Scourge of War series WGs - Nothing else quite like them. ( other than Graviteam )

Scourge of War series of WGs. ( Waterloo , Quatre Bras, Ligny, Wavre) and the Civil War series (Gettysburg, Chancellorsville, Antietam, Brandy Station, and Pipe Creek. These games are a sequel to Take Command: Bull Run and Second Manassas.

Interesting. I would like to see them updated and "fixed" (i.e. made more accurate).
