It had some more plays, and I did incorporate the CCN Expansion 5 rules into the variant rules, specifically the Grand Battery rule and the Tactician Cards (which were made by Michael D)
I can't recall if where I loaded those, so I have attached again
In terms of my satisfaction with the rules, they are mechanically reliable, and they did address the problem of the two sides essentially rushing towards each other. It has strengthened defense and made lines more stable, in the same manner as C&C Napoleonics.
Something I hadn't anticipated is the need to strengthen the attacker in the scenarios. The Tactician cards should do so, but I'm not experienced enough with them in BC to say for sure. Something I think would be better is a new set of Tactician cards, but a separate Union and Confederate sets. Union would have more artillery cards, and perhaps Rally cards. Confederate more cavalry and Infantry assault cards.
The variant absolutely demonstrates the problem infantry faced when using Napoleonic style command and tactics versus rifled weapons. Crossing open ground is very difficult, and ranged firepower is the main combat.
