With the land game going so well, Mike and decided not to add in the complexity of the ironclads and left them more as color than true game influencers. We put them on in case one side ended up running way with the game to even out things (they have really big guns) but never needed to use them. I firmly believe the primary role of a GM at a con game is to ensure everyone has a good time and I'm not above "re-balancing" a game if needed. This game needed no rebalancing given the great players we had.
I was extremely pleased with how the Longstreet rules worked in a convention setting. We essentially used the Longstreet "lite" version which simplifies the game but it was both easy to teach and the players were able to play the game without guidance after the third turn. To be honest, my favorite ACW rules are still Regimental Fire and Fury but Longstreet is a very close number two and a great option for beer and pretzel gaming or cons. It will likely be my goto rules for ACW at cons going forward.
