RollerCoaster Tycoon 2 (or RCT2 for short) is the second installment in the RollerCoaster Tycoon series. Like in its predecessor, the player must build successful theme parks to fulfill a set of objectives in various scenarios. The game was further expanded with two expansion packs, Wacky Worlds and Time Twister, which brought more themes and theme-inspired derivatives of existing rides, as well as new scenarios. These two add-ons were not worked on by Chris Sawyer.
