Tonight Dave, Kent and I got together to try and suss out the rules we'll be using at the weekend. Dave and I used my Hood Division force (we will be sharing the command over the weekend) and Kent used a similarly sized Union force. We played through a few turns to get a feel of the rules and I must say I quite like them. As with all rules I felt that some tweaking might be in order (such as maybe taking a loss if disordered for a second time and I'v heard some groups don't allow rear rank to fire but it would be a few more games before I'd make my mind up for sure). Overall though the rules were pretty intuiative and gave a good feel. It will be interesting to see how they handle 20+ players over the weekend.
Sorry was a bit busy flicking through the rulebook to take many photos.
