Glossary
code (light on, heavy on, code-base) Code is loosely used to describe what kind of system a MU* runs on, and the amount of commands that the system uses. A game that is light-on-code has few extra commands and relies more on imagination and player responsibility. A game that is heavy-on-code may have commands for everything down to eating, phones, cars, housing, etc. on one hand they're usually designed for players to be able to do a lot without needing the assistance of the games staff, on the other hand it also tends to restrict imagination and unusual uses of props.
FC(s) - Feature Character(s). Feature Character is a phrase that can have different meanings based upon the game system being played. For comic-book, movie & TV based games it traditionally refers to a character from the source material (e.g. Wolverine from the X-Men), but for RPG-based games (like Whitewolf, Star Wars, etc) it usually refers to a more-powerful-than-average character.
Furry - For online games, players who favor anthropomorphic characters. Unfortunately usually assumed to be TS-fiends.
PC(s) - Player Character(s). These are characters run by players, as opposed to NPCs.
MU* - Stands for 'Multi-User', a phrase used to refer to online RPGs regardless of their base code-system. See also: MUCK, MUD, MUSH, MUX.
MUCK - Unknown what it stands for. Considered to be the 'beginner's MU*' in some circles, MUCK is light on code, and what it has usually comes with fairly substantial explanations on how to use it. They're usually /very/ light on combat, and thus have gained large popularity with the Furry crowd.
MUD - Stands for 'Multi-User Dungeon', one of the earliest (if not THE earliest) form of MU*. MUD is heavily coded, and will typically come with an in-game tutorial for its most common commands. They are usually almost exclusively combat games.
MUSH - Stands for 'Multi-User Shared Hallucination', one of the most common forms of MU*. Runs the gamut between light-on-code and heavy-on code, typically tries to strike a balance between the personal growth style roleplay & the combat roleplay.
MUX - Unknown what it stands for. One of the most common forms of MU*. Like a MUSH, a MUX can be light on code, or heavy on code, and typically tries to strike a balance between the personal growth style roleplay & the combat roleplay.
NFC(s) - Non-Feature Character(s). Non-Feature Character is a designation usually used for comic-book, movie & TV based games, and refers to a character that was invented by the player rather than found in the games source material.
NPC(s) - Non-Player Character(s). These are GM or player run props. Temporary characters. The bartender or the taxi-driver or a guy running down the street.
TS - Usually refers to 'Tiny-Sex', a graphically descriptive scene of sex between two (or more) players. A 'TS-fiend' is a player whose only interest online is in roleplaying out these kinds of scenes.
