What is "replay value"

n. (context video games English) The entertainment value obtained by playing a computer game more than once; replayability.

Replay value or replayability is a term used to assess a videogame's potential for continued play value after its first completion. Factors that influence replay value are the game's extra characters, secrets or alternate endings. The replay value of a game may also be based entirely on the individual's tastes. A player might enjoy repeating a game because of the music, graphics, game play or because of product loyalty. Dynamic environments, challenging AI, a wide variety of ways to accomplish tasks, and a rich array of assets could result in a high replay value.
