Downloadable Content
Downloadable Content or DLC refers to content for a commercially distributed game, usually created by the original development studios and published by the publishers for the purpose of extending the game. This can range from simple new skins or new maps to new modes or game types, but can also add new single-player campaigns or alter the game entirely. In contrast to mods, the source is not the community but the original game owners. DLCs may or not may cost additional money, which also creates critic of the practice to provide plenty of DLCs, that actually only add minor new content but are charged money for in an unfair fashion. This can even lead to the situation, where DLCs create the majority of profit, not the original game itself. Some publishers are even having a reputation to practice this a lot, such as the publisher Electronic Arts.
