Фуркадия: Бесконечный мир, созданный игроками.

Furcadia is a free to play MMOSG/MMORPG or graphical MUD, set in a fantasy world inhabited by magical creatures. The game is based on user created content with emphasis on world building tools, exploring, socializing, and free form roleplaying. Furcadia hosts a large volunteer program called the Beekin Helpers, allowing players to help with community moderation, welcoming new players, handling in game technical support, running in game events, creating art for the game itself, accessing and updating the game's website, and bug hunting. Furcadia holds the Guinness World Records title for the longest continuously running social MMORPG and, in addition to being one of the first games to heavily encourage modding and let users build virtual worlds for themselves, it was also one of the first freemium online games. In 2008, Furcadia was reported as having over 60,000 players.

The character, or avatar on Furcadia can be set to one of 11 free species, including both humans, insects, and anthropomorphic animals. Players can choose between one of three genders: male, female, and unspecified. These genders modify the default portrait, butler (the large character art), and specitags, icons seen to the left of players' names in chat.

Players can customize their avatars by choosing colors from a palette. These colors are shown on the butler, walkabout, and portrait. The walkabout has a walking animation with the ability to stand, sit, or lie down. There are default portraits for each avatar, however, players may upload a 95x95 custom portrait for a small fee. 22 Custom avatars (non gendered) may be added and used inside private dreams, for free. Each character can also have a written description, which can include character details, external links to websites, or internal links to private dreams. Some players choose to link to third party websites to extend their descriptions beyond the character limit the standard Furcadia description allows.

The primary focus of Furcadia is user generated content. To this end, the Furcadia game download includes an art editor, a map creating program, a skin editor, and a script editor. Users are encouraged to create their own virtual worlds, called Dreams, using these free tools. These worlds can be uploaded to the Furcadia server for free and used for a variety of purposes, examples being text based role playing, a place to hang out with friends, or playing multiplayer games and quests with other users, etc. Dreams remain open to the public area 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.

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.

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.

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 based on age groups, ranging from Everyone8+ to Adult Only, with specific behavior, language, and content restrictions. Some main maps—FurN and Hawthorn (previously Haven/New Haven)—immediately block the user from entering the main map if they are not within the specified age group and parental controls are enabled.
