Tripods and Hussars is Ty Beard's set of rules for playing battles set in HG Wells' War of the Worlds universe.
The Soldiers of the Queen site is a great resource for anyone who games with Victorian Era miniature soldiers. The site is stuffed full of photographs from the era. A must see.
And now for something completely different. But maybe still useful.
I. Marc Carlson has written an artcle on medieval breeches. Yes, pants. There are a number of illustrations, and this interesting fact: no actual medieval breeches have survived to this day, so no one is really sure how they were constructed.
Still, its a useful resource for sculptors and painters.
Vaporoare is a role playing game, but as is the case with such, it's full of ideas for skirmish type miniatures games. The author writes:
Vaporoare is a role-playing game of weird science and mad magi in Victorian-era Europe. It imagines a world where Jules Verne wrote technical manuals for ether machines instead of fiction; Mary Shelley penned the autobiography of Dr. Frankenstein, and H. P. Lovecraft didn't know what he was getting into. It is the world described by Edgar Allan Poe, Lord Dunsany and J. R. R. Tolkien. Europe is alive with races of fiction: elves dwarves and gnomes. These people have lived together since the beginning of time, and now they face their greatest challenge: the Industrial Revolution. Magick is dying, and technology is on the rampage.
GASLIGHT is probably the most played set of Victorian Science Fiction miniatures rules available today. The Rivets and Steam site has a page of houserules for the set.
