RolerCoaster Tycoon 2:
Building on the foundation laid by Chris Sawyer's original RollerCoaster Tycoon and its expansion packs, Loopy Landscapes and Corkscrew Follies, RollerCoaster Tycoon 2 offers more of everything fans of the series have come to love. The basic premise remains the same: players are challenged to create a thriving theme park that houses roller coasters of their own design. Scenarios are provided that test the player's management and creative abilities, and task would-be moguls with attaining specific milestones such as a certain amount of money made from ticket sales, repayment of a hefty bank loan, and other such objectives pertaining to the success of the park. Unlike previous iterations, the 26 in-game scenarios can now be tackled in any order the player desires.
As before, players are given full control over the creation of their gravity-defying rides, allowing for whatever inclines, steep lifts, corkscrews, and drops that paying customers can handle. Of course, rides must strike a balance between fun and technical achievement or patrons won't ride on them, hurting the bottom line. Additions in this sequel include new roller coaster and ride variants such as the Giga Coaster and Spinning Wild Mouse, along with new scenery, animations, and attractions like ATM machines. The scenery is tied into the themed nature of the parks, and ranges from Old West to medieval motifs.
Fans of real-life coasters will be pleased that they'll have access to actual Six Flags roller coasters, taken from five different Six Flags parks such as Magic Mountain and Six Flags Great Adventure. They can even make adjustments to the actual Six Flags parks themselves, customizing them to their liking. A scenario and roller coaster editor are included, the latter allowing players to construct their dream roller coaster away from the demands and constraints of the scenario-based missions. The scenario editor, on the other hand, provides players with the ability to create custom, stand-alone missions with user-defined scenery, landscape, shops, rides, winning conditions, and other variables.

RollerCoaster Tycoon 2 - Wacky Worlds:
The first expansion to RollerCoaster Tycoon 2 lets virtual coaster park owners expand their horizons with its offer of 17 scenarios in locations from all seven continents. Wacky Worlds features three scenarios each from Africa (Victoria Falls, Diamond Mine, Oasis), Asia (Japanese Coastal Reclaim, Great Wall of China Tourism Enhancement, Maharaja Palace), North America (RollerCoaster Heaven, Hawaii, Grand Canyon), and South America (Rain Forest Plateau, Rio Carnival, Inca Lost City). Both Australia (Ayers Rock, Fun at the Beach) and Europe (European Cultural Festival, Renovation) host two new scenarios, while Antarctica accounts for the final Icebergs theme.
In addition to the scenarios, more than 50 new rides showcase landmarks from around the world like the Taj Mahal, Eiffel Tower, Big Ben, Great Wall of China, Mount Rushmore, Leaning Tower of Pisa, Golden Gate Bridge, and Incan ruins. Wacky Worlds includes more than 200 new game elements along with continued support of the Ride Exchange from the official RollerCoaster Tycoon 2 website. Gameplay requires installation of RollerCoaster Tycoon 2 as well as the presence of the original game disk in the CD-ROM drive.
