"RollerCoaster Tycoon (or often abbreviated RCT) is a series of computer games that simulate amusement park management. Each game in the series challenges players with open-ended amusement park management and development, and also allows players to construct and customize their own unique roller coasters.
The first game of the series was developed by designer and programmer Chris Sawyer, artist Simon Foster and composer Allister Brimble. It was published by Hasbro Interactive (which was sold to Infogrames, and is now known as Atari). The game was a sleeper hit. It spawned two sequels and several expansion packs."
