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