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.

Mateen Greenway has produced an amazing set of 3D computer images of victorian science fiction vehicles, including cloudships, ether flyers and cities on Mars. Its a great bit of inspiration.
