Atari announced that Atari will become the publisher of Rollercoaster Tycoon 3 developed by Frontier Developments plc. Released in 2004, the title is available on PC, Mac, iOS and Nintendo Switch. Atari is now the sole publisher of all major titles within the Rollercoaster Tycoon franchise.

The purchase price of Roller Coaster Tycoon 3 consists of an initial consideration of USD 4 million as well as potential deferred cash consideration of USD 3 million. Rollercoaster Tycoon 3 contains the three core modes of most franchise games: scenarios in which players must accomplish specific goals, a tycoon mode where players unlock new rides and tools as they progress, and an open sandbox. The game also introduced some new features to the franchise.

The biggest change was a switch from a fixed isometric viewpoint to 3D graphics. Other new features included CoasterCam which allows players to ride their coasters in a first person view, Mixmaster which allows users to choreograph fireworks to music, and enhancements to peeps, adding variations in age and gender, and introducing groups of peeps. Atari now publishes franchise titles across PC, console and mobile including Rollercoaster Tycoon Classic, Rollercoaster Tycoon 2, Rollercoaster Tycoon 3, Rollercoaster Tycoon Deluxe, Rollercoaster Tycoon Joyride, Rollercoaster Tycoon World, Rollercoaster Tycoon puzzle and Rollercoaster Tycoon Touch.

Atari manages the Rollercoaster Tycoon franchise under a long-term licensing agreement with the franchise's creator Chris Sawyer. Under the agreement, Atari will seek to develop new titles, expand digital and physical distribution, and explore brand and merchandising collaborations as part of a long-term plan to bring the franchise to new heights.
