An '''expansion pack''', '''expansion set''', '''supplement''', or simply '''expansion''', is an addition to an existing [[role-playing game]], [[tabletop game]], [[video game]], [[collectible card game]] or [[Miniature wargaming|miniature wargame]]. An expansion may introduce new rules or [[game mechanic]]s that augment the original game and add more variety to playing it. In the case of video games, they typically add new game areas, weapons, objects, characters, adventures or an extended [[Plot (narrative)|storyline]] to an already-released game.<ref>{{Cite web |title=What is an Expansion Pack? |url=https://www.computerhope.com/jargon/e/expansion-pack.htm |access-date=2023-09-04 |website=www.computerhope.com |language=en}}</ref> 

While board game expansions are typically designed by the original creator, [[video game developer]]s sometimes contract out development of the expansion pack to a third-party company, it may choose to develop the expansion itself, or it may do both.

Board games and tabletop RPGs may have been marketing expansions since the 1970s, and video games have been releasing expansion packs since the 1980s, early examples being the ''[[Dragon Slayer (series)|Dragon Slayer]]'' games ''[[Dragon Slayer II: Xanadu|Xanadu Scenario II]]''<ref name="Xanadu">{{cite web|author=Kurt Kalata|url=http://www.hardcoregaming101.net/xanadu/xanadu.htm|title=Xanadu|publisher=Hardcore Gaming 101|access-date=2011-03-25}}</ref> and ''[[Sorcerian]]''.<ref>[http://gamecola.net/2010/10/sorcerian-pc/ Sorcerian (PC)], ''GameCola.net'', 30 October 2010</ref> Other terms for the concept are '''module''' and, in certain games' marketing, '''adventure'''.{{Citation needed|reason=This is neither cited nor expanded upon below|date=July 2018}}

==Characteristics==
The price of an expansion pack is usually much less than that of the original game. As expansion packs consist solely of additional content, most require the original game in order to play. Games with many expansions often begin selling the original game with prior expansions, such as ''The Sims Deluxe Edition'' (''[[The Sims]]'' with ''[[The Sims: Livin' Large]]''). These bundles make the game more accessible to new players. When games reach the end of their lifespan, the publisher often releases a 'complete' or 'gold' collection, which includes the game and all its subsequent expansions.

==Stand-alone expansion packs==
Some expansion packs do not require the original game in order to use the new content, as is the case with ''[[Half-Life: Blue Shift]]'', ''[[Uncharted: The Lost Legacy]]'', ''[[Dishonored: Death of the Outsider]]'' or ''[[Sonic & Knuckles]]''. Some art, sound, and code are reused from the original game.  In some cases, a stand-alone expansion such as ''[[Heroes of Might and Magic III: The Shadow of Death]]'', or ''[[Dungeon Siege: Legends of Aranna]]'' includes the original game.

==Console game expansion packs==
Expansion packs are most commonly released for [[PC game]]s, but are becoming increasingly prevalent for [[video game console]]s, particularly due to the popularity of [[downloadable content]]. The increasing number of multi-platform games has also led to the release of more expansion packs on consoles, especially stand-alone expansion packs (as described above).  ''[[Command & Conquer 3: Kane's Wrath]]'', for example, requires the original ''[[Command & Conquer 3: Tiberium Wars]]'' to play on the PC, but Xbox 360 versions of both the original ''Tiberium Wars'' and ''Kane's Wrath'' are available, neither of which require one another.

The Japanese version of [[Konami]]'s ''[[Beatmania]]'' was the first game on the [[PlayStation (console)|PlayStation]] to support expansion packs, which were branded as append discs.<ref>{{Cite web |date=October 17, 2024 |title=Beatmania |url=https://www.mobygames.com/game/27184/beatmania/ |url-status=live |archive-url=https://web.archive.org/web/20240716011803/https://www.mobygames.com/game/27184/beatmania/ |archive-date=July 16, 2024 |access-date=October 17, 2024 |website=Moby Games}}</ref> These discs included additional tracks and required the original Beatmania disc (and later playable Beatmania game discs) to play. The discs required the player to access the Disc Change menu on the Beatmania disc, remove the Beatmania disc, insert an append disc, then press the start button to play. The first append disc for the game, Beatmania Append Yebisu Mix, was bundled with the PlayStation version as the game's 2nd disc, with subsequent append discs being released as standalone retail releases.

''[[Grand Theft Auto: London 1969]]'' was marketed as the first expansion pack released for the PlayStation.<ref>{{cite web|url=http://www.gamespot.com/articles/take-two-ships-gta-london-1969/1100-2451809/|title=Take-Two Ships GTA: London 1969|work=[[GameSpot]]|first=Sam|last=Kennedy|date=27 April 2000|access-date=7 January 2017}}</ref> The game required the player to insert the ''London'' disc, remove it, insert the original ''[[Grand Theft Auto (game)|Grand Theft Auto]]'' disc, remove it, then insert the ''London'' media again in order to play.

''[[Sonic & Knuckles]]'' for the [[Sega Genesis|Mega Drive/Genesis]] was unusual in that it functioned as both a stand-alone cartridge and as an expansion pack for both [[Sonic the Hedgehog 2 (16-bit)|''Sonic the Hedgehog 2'']] and ''[[Sonic the Hedgehog 3]]''.

==Collectible card game expansions==
Collectible card games, or CCGs for short, are typically released as expansion sets, composed of [[booster pack]]s.<ref name="LEE">
