in which they are uploaded, so long as it is inhabited, and, if unoccupied, it is eventually unloaded automatically. While there are several types of dreams that are popular, users continue to create new things with the tools they are given. Furcadia hosts a variety of roleplaying dreams, ranging from strict-continuity roleplay (in which the dream is its own independent world) to persona play. Roleplaying dreams also come in a number of different forms, ranging from feral (wild animal) to furre (anthropomorphic animal) to human. Many dreams revolve around fantasy plots and themes, based on popular books, television programs, ancient mythology, or original creations of Furcadia players. Furcadia itself is basically made up of several dreams, the ones made by its users and the main maps. Patches Almost all of the 6,000+ default art files shown in Furcadia can be patched over and displayed in a Dream, including the skin, buttons, avatars, items, walls, effects, lighting, ambience, portals, and floors. Additional art may be added to a Dream in file types ending with 'e', such as iteme, floore, etc., which does not overwrite the default art. Much user created patch art is available for download via third party websites. Dreams can also include the use of audio files in the WMA, Ogg, MOD, S3M, WAV and MIDI (.mid) formats. Scripting Players may add interactivity to dreams chiefly through a custom scripting language known as DragonSpeak, or "DS". DragonSpeak commands may be triggered by in-game actions or by custom buttons displayed over the game interface. Other custom scripting tools include PhoenixSpeak, which is used to store information to a permanent database, and an animation scripting language called KitterSpeak. These scripting languages enable players to script actions ranging from the simple, like opening a door, to the more complex, such as a complete game of chess or laser-tag. Dream owners are allowed to make and use bots to accomplish things that DragonSpeak cannot, but these are not officially supported by Furcadia. Dream standards Although Furcadia itself is unrated, individual dreams may specify a standard which details what kind of behavior, language, and content may be allowed. Before March 2007, Furcadia used a rating system akin to the MPAA film rating system. Since March 2007, Furcadia uses its own Dream standards system which allows users to define exactly what kind of behavior should be allowed on a per-dream basis. The Dream standards are
