RollerCoaster Tycoon World is a theme-park building and management simulation centered on designing attractions and keeping guests happy. Its 3D coaster editor lets players shape tracks freely, while deformable terrain, curved paths, and freely placed objects make the park itself part of the design work. Coasters also use a physics simulation, and players can ride their own creations from the front seat.
The game offers two distinct ways to play. In Progression Mode, a mission-based campaign across three world maps sets objectives and awards Research Points, which unlock scenery for Sandbox Mode. Sandbox instead gives players unlimited resources, with access to the full range of attractions and other items. Park management tools cover finances, guest feedback, and services such as medical care, cleaning, entertainment, and maintenance.
Custom-building and sharing extend the park-making focus: piece-by-piece tools support buildings and scenery, and Steam Workshop lets players share creations including coasters and parks.
