Modding
From GameLabWiki
Modding, modifying or adding is a popular practice in digital games. It is defined by the intervention and manipulation of a game at hardware or software levels that change the game design in graphics and mechanics in a way that was not intended by the original developers. One of the most popular modifications is the game Counter Strike, which was created out of the game Half Life. But while this modifications transformed to a whole new game, other modifications are only supposed to ad smaller changes to an exiting game. Prime examples for such partial modifications are for instance the game Minecraft (2009) from Mojang or the game The Elder Scrolls V: Skyrim (2011) from developer studio Bethesta.
