I actually wrote a piece in the Christmas Special on 1914 tactics and representing forces with Mud & Blood (British and German, no French yet). I focussed that action on a small historical rearguard action during the retreat to the south west of Mons. I found it an interesting game to play through as the Germans do have huge command and control issues, but they have a much larger platoon.
We have a piece on converting IABSM for the Great War in one of the older Specials (I think it was in 2007) called Sturmabteilung Vor! which sounded really interesting. I never played it, but I keep meaning to. I have actually been working on some Divisional level rules for the Boer War as a precursor to they extending that to the Great War. You really do get distinct operational boundaries at that level so the battle you fight can be discrete to that Division, but with just some Corps guns added to the mix. Something like the 36th Ulster Division on July 1 1916 would be an interesting action to fight.
Some of the most enjoyable games I have ever had have been kriegsspiel type games played on British Army 1:100,000 maps of the period using some rules we wrote called "Corps Blimey". We have refought a number of major actions such as Amiens 1917 in an evening. They are really absorbing games but rattle along at a fair pace. I have the whole western front covered by my map collection so I am lucky in that I can really do any actions I fancy with that. Save a lot of painting too!
