Definitions for "MUDs"
Multi-User Dungeons/Domains. These are pretty cool creations of the net. On them, you can have real-time interaction with as many as 100 other people who have connected into the same MUD. Some MUDs are action/adventure-oriented, where you go out and kill monsters and gain experience like in D&D, while others are social-oriented, where you build areas for other's enjoyment, and interact with other people more. I think they're all just neat. The one I hang out on is called Overdrive, and I'm known as Kamikaze on there if you happen to stop by.
and MOOs MUD stands for Multi-User Dimension or Multi-User Dungeon, from its origins as an electronic version of fantasy games such as Dungeons and Dragons. MUDs are synchronous (real-time) virtual reality spaces, where participants act out character roles in imaginary worlds, all described in text. The social nature of MUDs can be reflected in elaborate reward and punishment systems. MOO stands for MUD, Object-Oriented. MOOs use software that allows participants more control over constructing the virtual space. Many MOOs have been devoted to educational, scholarly, or community purposes, as opposed to the game-orientation of the early MUDs.
Interactive real-time, text-based games accessible to anyone on the Internet.
