A good portion of one wall of the miniatures gaming room was taken up by an expansive Victorian science-fiction game using the Gaslight rules.
The scenario pitted a group of adventurers (led by Sherlock Holmes) against his arch-nemesis Professor Moriarty, who had kidnapped Queen Victoria.
A shadowy figure known as Von Lostanarm was also involved, as were a small force of Belgians, a tribe of pygmies, a steamship, and a pair of Arab dhows.
Also on hand, but not in action at the time I saw it, were a zeppelin, a British land dreadnought and some other mechanical constructs.
