The mudpy project aims to create a simple, generic, cross-platform, freely-redistributable MUD core engine which can be easily understood and extended. It is written in pure Python (currently tested with 3.4 and later versions) and has only pure Python dependencies. All configuration and data are stored in consistently-formatted plain text (YAML 1.1) files for ease of administration. The core engine is unicode-clean internally and supports UTF-8 encoding for input and output of extended text characters.
The mudpy program and sample content are released under a free and open license, and any bug reports, criticisms, ideas, patches, content submissions or other offers of collaboration are wholeheartedly welcome.
