RollerCoaster Tycoon (abbreviated RCT) is a trilogy of video games that simulate amusement park management. Each game in the series challenges players with open-ended amusement park management and development, and allowing players to construct and customize their own unique roller coasters. One popular thing people do is run over people with roller coasters or make coasters that purposely crash.
Other popular fad players do is recreating Theme parks (Disney,Universal,Six Flags,etc.) on the games.
Mr. Bones Wild Ride
Another popular fad is Mr. Bones Wild Ride. A ride that never ends.
