What WorldForge is

WorldForge is a Free Software project for building virtual worlds and allowing others to experience them. It provides servers, clients, protocols and tools for Linux, macOS and Windows, with a 3D and multiplayer focus. World authors use Ember both to play and to create settings with custom terrain and entities. Deeds is the default medieval MMORPG world and can be adapted as a foundation for custom worlds. Its entities and interactions are described through declarative specifications and Python code, while gameplay emphasizes surviving and adventuring rather than killing to advance. Cyphesis supplies the server and can be installed from an operating-system package or built from source. Other components include Atlas, Eris, Mercator, Varconf, WFMath, Metaserver and Squall, which synchronizes client base assets and server updates. The WorldForge plan costs nothing. Contributors are welcomed in development, art, 3D sculpting, composition, sound and web design. The project notes that its worlds may still be rough around the edges and require further work. Community communication uses Gitter, while Launchpad handles bugs and feature planning.
