Information:
ScryMUD is a MUD written completely from scratch in C++.
ScryMUD has a full feature set, including persistent belongings, a tree-based skill and spell system, game-navigated vehicles, complex scripting, player-owned stores and much more.
The distribution also comes with Hegemon, a Java Client that gives a graphical interface to ScryMUD.
The program is especially nice because of the UI that it gives to ScryMUD's Online Building.
