Thanks for the nice comments.
The day was brilliant and I had an absolute blast! Thanks to everyone who came up and commented on it, and thanks to Alex and Jono (FaramirsMomma and OnjoTheRed) for coming down to catch up and finally meet face to face.
Here are some pics of the table in action:
Left to right: Greg (game designer and adjudicator), Ty (French), Mark (Nannies), Alex (British), Steve (Prussians - eventual winner of game #1).
Thanks also to Greg for running the game and to Ty for bringing along the most magnificent force of Frogs!
The steam boats were provided by Nic from Eureka (as were most of the minis) and the control room machinery was built by one of the Eureka sculptors (Kosta, who is responsible for much of the Pax range I believe).
It was a wonderful day and I wanted to say thanks to everyone involved.
