Player vs player

Player(s) versus player(s), better known as PvP, is a type of multiplayer interactive conflict within a game between two or more live participants. This is in contrast to games where players compete against computer-controlled opponents and/or players, which is referred to as player versus environment (PvE). The terms are most often used in games where both activities exist, particularly MMORPGs, MUDs, and other role-playing video games. 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 experienced and novice players. PvP can even encourage experienced players to immediately attack and kill inexperienced players. PvP is sometimes called player killing.

PvP combat in CRPGs has its roots in various MUDs like Gemstone II and Avalon: The Legend Lives.. However, while the ability to kill another player existed in many MUDs, it was usually frowned upon because of general strict adherences and heavy influences from role-playing games like Dungeons & Dragons. The term PvP originated in text based MUDs played on bulletin board systems like MajorMUD and Usurper. These games had open worlds where any player could attack any other player as long as they were not at a safe spot in town like the Bank. Player versus player was coined sometime in the late 1980s to refer to the combat between players that resulted in the loser being penalized in some way.

The first graphical MMORPG was Neverwinter Nights, which began development in 1989 and ran on AOL 1991-1997, and which included PvP. PvP was initially limited to magical attacks in the game. Later modifications expanded its use to limited areas so that players who wished to avoid it could do so. Much of the PvP activity was coordinated events by the game's guilds, which were the first such organized user groups in MMORPG's.
