Genecys is a massively multi-player online RPG. It is a completely dynamic environment. Each server is completely unique and follows its own progression of events. Maps will be generated randomly, at server startup, as will towns and NPCs. NPCs will be AI controlled, and have their own lives in the game, and exist to interact with the players, not just to be slaughtered by the players.
Mudsbuilder is a set of tools for the creation of dungeon maps in MUDs. Once a map is created, the user has the ability to generate LPC code from that map for virtually any mudlib. It supports standard (south, north, east, etc.) exits, ups and downs, and miscellaneous exits, such as one-way exits.
Trebuchet Tk is a MUCK/MUSH/MOO GUI client written entirely in TCL/Tk. It supports both Unix/X11 and Windows, and includes powerful scripting, triggers, hilites, macros, quickbuttons, keybinds, etc. that you would expect from a good MU* client. It also supports MCP simple-edit, and GUI dialog packages for MOO and FBMUCK6. For Muck users, Trebuchet also supports intelligent colored editing of MUF and MPI programs.
Myth2 is an implementation of a binary tree and used to run an 'interactive story'. The user traverses down the tree and at each node is given a bit of story and two options to choose which path to follow. If there is no story after the option, the user is given the chance to add to the story. It is written in PHP 4 and uses MySQL for the backend. Output is fully XHTML 1.0 Transitional compatible and fairly flexible.
TinyMARE (Multi-user Adventure Roleplaying Epic) is a text-based MUD server completely rewritten for efficiency using TinyMUSH and TinyMUSE as a basis for its game engine. The server is designed for creating an extensive, novelistic role-playing atmosphere supporting real-time combat, day & night, seasons, and global weather. Using a telnet client, players can log on to explore a virtual world, find magical items, learn skills and techniques, and group together to surpass obstacles you create in your own epic adventure.
