Steampunk games
Steampunk is a science fiction style in which worlds are surrounded by steam technology: all automatic devices, vehicles, weapons and other technologies are based on steam engines. The clothes of the inhabitants of such worlds are also noticeably different from the usual fantasy ones (for example, leather vests, hats and trousers).
Games in the steampunk style throw the gamer into a similar universe, but many of them take only part of the style. One of the games that delved into this style as deeply as possible is Arcanum: Of Steamworks and Magick Obscura.
