Overview
Players became creators. Modding transformed consumers into developers, building new levels, characters, and game modes on top of commercial releases. Some mods became bigger than their source games—Counter-Strike started as a Half-Life mod, DOTA as a Warcraft III map. The line between player and developer blurred permanently.
