Although the core features of
Roller Coaster Tycoon 3 are based on the previous games,
Chris Sawyer, the developer of the first two games, acted only as a consultant, as the game was instead developed by
Frontier Developments, since Sawyer was developing ''
Chris Sawyer's Locomotion'' at the time. It is powered by the
Cobra engine.
Expansion packs Two expansion packs for
RollerCoaster Tycoon 3 were released –
Soaked! and
Wild!. A bundle,
RollerCoaster Tycoon 3 Gold, was also released, including the original game and the
Soaked! expansion pack; this was followed by
RollerCoaster Tycoon 3 Platinum (Deluxe for the EU version of the game), including both expansion packs and the original game.
RollerCoaster Tycoon 3 Platinum is available for
Windows and
macOS. The game was also published by Aspyr Inc. on the
Mac App Store in 2012.
Soaked!, the first expansion, allows the player to build
water parks, which include
swimming pools,
water slides and
underwater aquariums, while adding more rides and scenery to the original game such as the ability to create
waterfalls. Using the MixMaster feature, the expansion pack also allows players to make their own water-jet displays and co-ordinate them to music.
Soaked! received an average rating of 79 on
Metacritic.
Wild!, the second expansion, allows the player to build zoos and safari rides, similar to
Zoo Tycoon in an amusement park setting, in which animals can be placed, and adds more ride types and scenery to the original game. Additionally, it addressed several criticisms of the first game, such as the inability to build underground, which is available without the expansion pack in the form of an update patch.
Wild! received an average rating of 71 on
Metacritic. Frontier released an iOS port of
RollerCoaster Tycoon 3 on August 12, 2015.
Subsequent lawsuits and Complete Edition The original series' creator
Chris Sawyer sued
Atari in 2005 for allegedly breaching the terms of a licensing agreement by not allowing auditors access to accounts from 1999 to 2001, during which he claimed he was owed US$4.8 million. Atari counter-claimed in 2007 by claiming that Sawyer broke an agreement by signing a license-agreement with developer
Frontier Developments, allowing them to create a demo for console platforms based on assets and mechanics from
RollerCoaster Tycoon 3. It was claimed by Atari that this induced Frontier to breach its contractual obligations to Atari by allowing Frontier to market and/or elicit funding for
Thrillville through this demo. According to Atari, without this demo, Frontier would not have been able to create
Thrillville independently from Atari. The lawsuit ended with an out of court settlement. Later in May 2018, the game was pulled from both
Steam and
GOG due to "expiring rights". While no resolution of the case has been publicly stated, Frontier announced the release of a self-published version of
RollerCoaster Tycoon 3, named
RollerCoaster Tycoon 3: Complete Edition. Like
Platinum /
Deluxe, this release includes both
Soaked! and
Wild! expansions. Additions included in the
Complete Edition were to update the game to run on more modern computers, an adjustment in aspect ratios, and the removal of all references to the game's previous publisher -
Atari. Alongside this updated computer version, a console port for the
Nintendo Switch was also created. The
Complete Edition was released on September 24, 2020, to Steam,
Epic Games Store, and
Nintendo eShop. In March 2024,
Limited Run Games announced a physical version of the Switch release of
RollerCoaster Tycoon 3: Complete Edition. On the Mac App Store, the version published by Aspyr Inc. was updated to the
Complete Edition. On March 15, 2024, Frontier sold the publishing rights to the game back to
Atari, Inc. for $7 million. In a trading update published by the
London Stock Exchange on April 2, it was reported that Frontier made $1.5 million a year from their sales of
RollerCoaster Tycoon 3: Complete Edition on all platforms. This was confirmed by their parent
Atari SA on April 2. Anticipating the twenty-fifth anniversary of the
RollerCoaster Tycoon series, Atari SA CEO Wade Rosen said, "I am really pleased that we can unite this important and successful title in the series with the rest of the franchise." On February 18, 2025, Atari and Frontier Developments announced that the
Complete Edition would be released for the
PlayStation 4,
PlayStation 5,
Xbox One and
Xbox Series X/S consoles on March 20. ==Reception==
