Mod (computer gaming)

A mod, or modification, is the alteration of content from a video game in order to make it operate in a manner different from its original version. Mods can be created for any genre of game but are especially popular in first-person shooters, role-playing games and real-time strategy games. Mods are made by the general public or a developer and can be entirely new games in themselves, but mods are not stand-alone software and require the user to have the original release in order to run. They can include new items, modded weapons, characters, enemies, models, textures, levels, story lines, music, money, armor, life and game modes. They can be single-player or multiplayer. Mods that add new content to the underlying game are often called partial conversions, while mods that create an entirely new game are called total conversions and mods that fix bugs only are called unofficial patches.

Games running on a personal computer are often designed with change in mind, allowing modern PC games to be modified by gamers without much difficulty. These mods can add extra replay value and interest.

The Internet provides an inexpensive medium to promote and distribute user created content like mods, an aspect commonly known as Web 2.0. Video game modding was described as remixing of games and can be therefore seen as part of the remix culture as described by Lawrence Lessig. The Mods have become an increasingly important factor in the commercial success of some games. Developers such as id Software, Valve Corporation, Mojang AB, Bethesda Softworks, Firaxis, Crytek, The Creative Assembly and Epic Games provide extensive tools and documentation to assist mod makers, leveraging the potential success brought in by a popular mod like Counter-Strike.
