Worlds and Time Twister—rose to 7 million copies by April 2004. The NPD Group declared Rollercoaster Tycoon 2 the 10th-best-selling computer game of 2002, and the 12th-best-selling of 2003. In the United States, RollerCoaster Tycoon 2 sold 940,000 copies and earned $21.6 million by August 2006. Edge ranked it as the country's eighth best-selling computer game released between January 2000 and August 2006, and as the country's best-selling RollerCoaster Tycoon game released in that period. RollerCoaster Tycoon 2 also received a "Gold" sales award from the Entertainment and Leisure Software Publishers Association (ELSPA), indicating sales of at least 200,000 copies in the United Kingdom. Legacy Several user-created rollercoasters received media attention after footage of them were posted on various imageboards and social media. The RollerCoaster Tycoon series spawned a popular Internet meme based on a series of posts made in 2012 on 4chan featuring a slow, 30,696 foot ghost train track ride made in RCT2 called "Mr. Bones' Wild Ride" that took four in-game years to complete, leading the passengers in the game to express "I want to get off Mr. Bones Wild Ride". At the ride's conclusion, while the passengers were being guided back to the entrance to the ride, they were then greeted by a skeleton prop with a top hat, with a sign stating "The ride never ends". Both phrases have become popular memes. OpenRCT2 In April 2014, an open-source software project, OpenRCT2, was launched to enhance the gameplay of RollerCoaster Tycoon 2, including fixing bugs and allowing the game to run natively on macOS and Linux. The project replicates RollerCoaster Tycoon 2s gameplay with alterations such as support for high-definition resolutions, the substantial raising of software limitations on parks, and improved pathfinding. The port features UI themes, fast forwarding, enhanced localization, OpenGL hardware rendering, additional cheat codes, autosaving and larger screenshots. The project began as a one-man endeavour by the software developer Ted John, but has since had over 250 contributors improve the game. In order to create an accurate clone, the game was incrementally reverse engineered and re-written in the C programming language. As of May 2019, OpenRCT2 is compatible with the Nintendo Switch. PC Gamer praised the increased scope for creativity with the new toolset, adding: "you can build the park of your dreams with coasters that no sane person who values their intestines would think about riding. It’s a great way to return
