Furcadia is a free to play MMOSG/MMORPG (Massively Multiplayer Online Social Game/ Roleplaying Game) or graphical MUD, set in a fantasy world inhabited by fantasy 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 was one of the first games to heavily encourage modding and let users build virtual worlds for themselves. In 2008, Furcadia was reported as having over 60,000 players.
