Steampunk is a compound word, which is composed of steam and punk punk. Steam naturally represents the large machinery powered by steam engine. Punk, on the other hand, is a kind of non mainstream marginal culture. It is a style written in street language dialogue. Its significance lies in the style independence of the theme, rather than anti social. Steampunk's works often rely on some hypothetical new technology, such as new energy, new machinery, new materials, new means of transportation, etc., to show an overhead world outlook parallel to the 19th century western world, and strive to create its fictional and nostalgic features.
Although Steampunk has certain scientific elements, it is not rigidly attached to it. Einstein once said that imagination is more important than knowledge. Steampunk is built on the basis of the industrial science revolution, showing the space that does not exist in reality, so that players can see things they have never seen, and bring them happy themes. Its real value is to provide players with a broad imagination space, stimulate their imagination, and give them edification in this respect.
