I had the privilege of being invited to play in a Waterloo BBB game at Shrivenham. I was going to write a full report but one of my fellow players, Steve J, has beaten me to it. Rather than replicate what he's done, let me point you to his lovely full photo-AAR here. Likewise Stu on his Cirencester Wargames blog here.
Apart from echoing his thanks to our hosts, comrades and opponents for their good company and an excellent day, I'd just add one photo and one Reflection of my own:
Replayability. I suppose I've fought Waterloo five or six times now. Each one has played out differently to some degree. This time was radically different again, the French following a plan I'd not seen before and producing a shape to the battle that I'd not seen before. That plus the fact of it coming down to the last objective changing hands with the last dice on the last turn made it a seriously good game.
