Uses
Game replays are commonly used in the prevention and detection of cheating, especially when used in electronic sports. Game replays are often watched to develop skill at a game, by watching better players and their techniques and build orders. Replays are also used to raise stature in a particular game's community, and entire websites are dedicated to the replays.
Replays are the driving force behind replay reviews. A replay review can be loosely defined as a review of a game replay by an experienced player to determine what can be done to improve and expand upon the initial gamer's skill. Entire websites are dedicated to these reviews, such as Gamereplays.org.
