We did a test run of the GDB rules at Outland, the local game store, me and Gunfreak over at Apartment of War pooled our collections and arranged a small battle for five players.
It was 11 French battalions with three cavalry regiments and artillery support against a joint Prussian, British and Portuguese force supported by four cavalry regiments and artillery. Completely unhistorical of course, but loads of fun was had by all of us.
The battle was decided by the collapse of the Prussian brigade on one of the flanks, and by the fortunate (?) fact that the British cavalry never received orders to charge the exposed French flank on the other side of the table before the Prussians collapsed.
The first couple of turns went slow but at the end we were going at a reasonable pace. I am sure we did some things wrong with regards to the rules but that will sort itself out once we play more.
