I forgot to mention an important aspect of Steampunk yesterday. It’s very important because it’s an element very common to all aspects of the genre:
Both in terms of the visual style and the mannerisms of the genre, the basis is the
Victorian era. So: many of the adult males have mutton chops or long handlebar mustaches, many people have pocket watches, and there is an abundance of top hats, corsets, and parasols.
There are no airplanes; there are dirigible lines. Some stories have robots, but they’re clockwork automatons.
Guns exist since gunpowder does for centuries. For the genre, they tend to be pistols, shotguns, and rifles. There are no automatic weapons or machine guns — though prototypes of these things might exist for the story.
This gives me an idea for a list to come soon: a list of Steampunk-themed properties.
