The game also contains a variety of new themes and music for attractions.

Many popular rides in Six Flags amusement parks can be used in other scenarios, but are locked from editing.

Walibi Holland and Walibi Belgium were also under the Six Flags brands during development and were also included. Players can make and test their own roller coasters to save them for use in other levels with the Roller Coaster Designer, and the game includes a licensed promotion by Six Flags to include their own content and scenarios based on five of their amusement park branches, including Magic Mountain, Great Adventure, and Over Texas. A scenario editor is introduced, which allows players to create their own scenarios, creating the landscape, setting objectives, and selecting available rides and scenery. The 'bulldozer' allows the player to remove multiple pieces of scenery instead of only one piece at a time. User-created scenery items make a debut in this title. Some old ride designs have been merged with others. Many of the rides from the original RollerCoaster Tycoon have been modified and/or renamed. The mechanics in the predecessor made custom building construction less efficient, and rides and shops previously could not be built at varying elevations in that game, only rides that had tracks could be built underground, since the first section of any ride had to be placed above ground. The game provides greater flexibility by allowing pieces of scenery, rides, and other structures to be placed at varying heights above and below ground. One notable difference from RollerCoaster Tycoon is a more robust system for building structures, in which one can lay each piece of wall and roof individually. The player must simultaneously balance the park's expenses and income. The player satisfies park visitors' needs by building facilities and services such as food stalls, bathrooms, souvenir shops, ATMs, and information kiosks, as well as by hiring staff.

Various attractions, including transport rides, gentle rides, thrill rides, roller coasters, water rides, and shops or stalls, can be added to the parks as well as landscaping and decorations. The game retains the isometric perspective of its predecessor, allowing for high compatibility with amusement parks made in the previous game. In RollerCoaster Tycoon 2, players manage amusement parks and attempt to meet various goals to complete assigned scenarios.
