Ghost

A feature included in time attack or time trial modes in video games allowing the player to review their previous rounds. In racing games, for example, a ‘ghost car’ may follow the last or fastest 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.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 their 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 have ghosts set by staff members and developers, often showing perfect routes and lap times.A variation of the feature, dubbed by Firemonkeys Studios as ‘Time-Shifted Multiplayer’, was implemented in the mobile racing game Real Racing 3. It works by recording the lap times of players in each race, and uses statistics from other players to recreate their lap times for the player to beat. These ghost cars can collide with the player and other vehicles, and are fully visible to the player.In some rhythm games, such as the Elite Beat Agents and Moero! Nekketsu Rhythm Damashii Osu! Tatakae! Ouendan 2, saved replay data can be used in one of the player slots in a multiplayer game.
