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.
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.
The Japanese version of Konami's Beatmania was the first game on the PlayStation to support expansion packs, which were branded as append discs.
Collectible card games, or CCGs for short, are typically released as expansion sets, composed of booster packs.
[6][7] CCGs generally do not have a core set that is reprinted indefinitely, instead, they are retired and replaced with new expansions on a quarterly or bi-annual basis.
