Multi-User Environment Server (MUES) is a multi-threaded, event-driven Internet game environment server written in Ruby. It is intended to facilitate the building of online multi-player games or simulations, by providing one or more dynamically programmed object environments (worlds), the means to access these environments (using a network client), various useful services or daemons (for creating in-game systems), and an event system (for facilitating the interaction of all the parts).
Reality is a client for Cyanide. Cyanide is intended to be the most dynamic multi-player online role-playing game ever made. This client uses an isometric perspective to present scenes. It is programmed with Python, pygame (SDL), and OpenGL. Full 3D movement is possible, and the server's code can be exchanged online.
DeltaMUD is a MUD server based on enhancements to the original CircleMUD bpl12 source code and is thus bound to the legal terms contained within the CircleMUD and DikuMUD license agreements. The goal of this project is to provide an enhanced, memory optimized, and SQL-based version of the original CircleMUD.
antioch is a Web application for building scalable, interactive virtual worlds. Begun as a MOO-like system for building virtual worlds, the goal was to take the LambdaMOO approach to creating online worlds, and update it in hopes of attracting new players to an old idea. Like many MOO clones before it, antioch uses Python as its internal scripting language. This provides a powerful environment for game authors, while a flexible object model allows for creation of complex in-game objects.
ymusk stands for Yenzie's Mush Klient. It is a mush client written in Perl, and it is built around the Net::Telnet and Tk modules. It is meant to be a simple program which is easily customizable. Its features include logging, macro definition, speech filters, command history, and ANSI colors.
