In video games, a ghost is a feature included in time attack or time trial modes allowing the player to review their previous rounds. In racing games, for example, a ghost car follows the path a player took around the track. In fighting games, the ghost is an opponent that the computer AI player can train against outside of normal player versus player or story mode.
Ghosts in racing games
Ghost cars in racing games generally appear as translucent or flashing versions of the player's vehicle. Based on previously-recorded lap times, they serve only to represent the fastest lap time and do not interact dynamically with other competitors. A skilled player will use the ghost to improve his time, matching the ghost's racing line as it travels the course. Many racing games, including Gran Turismo, F-Zero, and Mario Kart, offer a ghost function. Some also show ghosts set by staff members and developers, often showing perfect routes and lap times.
