I was staying down in London for a few days on a work-related trip. I took the opportunity to pop in to see the guys at the above club, which meets every Thursday evening in the function room of a pub near Mornington Crescent tube station - see their web page for details.
There were three really interesting games being played. One was a fictional clash between the Royal Navy anD the Russian navy at the time of the Russo Japanese War; another an Ancients game between the Byzantines and Arab, and a fun sci fi game of Stargrave, which benefited from great, largely home made terrain.
The members were great fun and very friendly. Pop along if you live in London or are visiting the capital.
