A multi-user dungeon, also known as a multi-user dimension or multi-user domain, is a multiplayer real-time virtual world, usually text-based or storyboarded. MUDs combine elements of role-playing games, hack and slash, player versus player, interactive fiction, and online chat. Players can read or view descriptions of rooms, objects, other players, and non-player characters, and perform actions in the virtual world that are typically also described. Players typically interact with each other and the world by typing commands that resemble a natural language, as well as using a character typically called an avatar.

Player versus player (PVP) is a type of multiplayer interactive conflict within a game between human players. This is often compared to player versus environment (PvE), in which the game itself controls its players' opponents. The terms are most often used in games where both activities exist, particularly MMORPGs, MUDs, and other role-playing video games, to distinguish between gamemodes. PvP can be broadly used to describe any game, or aspect of a game, where players compete against each other. PvP is often controversial when used in role-playing games. In most cases, there are vast differences in abilities between players. PvP can even encourage experienced players to immediately attack and kill inexperienced players. PvP is often referred to as player killing in the cases of games which contain, but do not focus on, such interaction.
