Expansions are major introductions of changes and content to EverQuest II requiring users to purchase the expansion in order to utilize the new content. Adventure Packs were mini-expansions, released between full expansions, that introduced new content to EverQuest II. The Adventure Pack concept has since been abandoned in EverQuest II.
