Tinyfugue is a very popular MUD/MUSH command line client rich in functionality. When using tinyfugue in a graphical environment the only thing it lacks is the peripheral buttons and options that are available to graphical clients. Gtinyfugue aims to embed tinyfugue within a GNOME wrapper that provides the GUI widgets that make tinyfugue easier and more comfortable to use on a day-to-day basis. Embedding tinyfugue rather than using simple telnet gives the gtinyfugue user the advantage of the depth of tinyfugue functionality.
The EQEMU project is an attempt to recreate the Everquest server software, runnable from a Windows or Linux machine. Content is stored in a MySQL database, and allows you to create custom creatures, items, and quest content in game. Many in-game functions are supported, and functionality is expanded week by week by a very active development group and by the support of the user community.
NFMCA is a MUD client with basic features in the form of a Java applet. The GUI is written with Swing, so one needs Java Runtime Environment to run it. Besides running in a browser as an applet, it also supports standalone mode. Features include dealing with a limited set of ANSI codes (foreground colors and underline), multiple languages (as you could expect from a Swing program) and font changing (two features which are absent in some much more complicated clients), smart scrolling, command history, detachment ability for applet mode, handy selection/copying mode, and more. It supports English as the default, and Russian for Russian-localized operating systems. NFMCA should run on any platform (tested on Windows and GNU/Linux).
