Replayability
From IFWiki
A quality of a game that holds the player's interest even after all the goals have been achieved and the game has been won. A highly replayable game may have easter eggs, optional puzzles, or may be structured so as to encourage multiple traversals. Also known as replay value; often an important influence on the purchasing decisions of game consumers.
