RollerCoaster Tycoon World is a theme park construction and management simulation video game developed by Nvizzio Creations and published by Atari for Microsoft Windows.

Players are able to build rides, shops and roller coasters, while monitoring elements such as budget, visitor happiness and technology research.

When building roller coasters, the game makes use of a spline system instead of the old style of laying individual pieces.

A new 'Park Pulse' mechanic was also introduced, allowing players to quickly find out how their park is doing and the customers' thoughts, similar to Zoo Tycoon titles.

[2] The game contains several scenery and ride themes at launch, with more in development that will be released via free updates and paid expansion packs.

[16] The developer noted the additional development time would allow them to add requested items and features such as "predefined piece" coaster building, additional coaster test feedback, a robust fencing tool, improved on-demand grid, and various smaller improvements.

[17] Atari had decided that its theme park game, RollerCoaster Tycoon World, would be launched into Early Access on 30 March, instead of going with a full release.

The early access release was met with negative reviews, mostly complaining about the poor graphics, coaster builder, lack of detail, and ride animations.

[20][21] A trailer released by Atari containing gameplay of RollerCoaster Tycoon World was received poorly by critics and fans.
