the United States totaled 719,535 units that year, for revenues of $19.6 million—the third-highest gross for 1999. Chris Sawyer said in response to the commercial success of the game, "I think everyone is a bit stunned by the sales success of RollerCoaster Tycoon, myself included. I always believed in the game concept myself, but I hadn't expected it to have so much widespread appeal among game players of all types." RollerCoaster Tycoon also received a "Gold" award from the Verband der Unterhaltungssoftware Deutschland (VUD) by the end of August 1999, for sales of at least 100,000 units across Germany, Austria and Switzerland. RollerCoaster Tycoon proceeded to become a long-term success in the United States. GameSpot's Trey Walker noted in late 2001 that it had "appeared in the top 10 [weekly sales] lists almost continuously" during its first two years of release. Domestically, it sold another 749,749 units and earned $20.32 million from January through October 2000, according to PC Data. These numbers rose to 1.25 million units ($32.99 million) by the end of the year, which made it the second-biggest computer game seller of 2000, behind The Sims. RollerCoaster Tycoons success continued in 2001: it placed again at #2 for the year, behind The Sims, and earned $21.9 million with 953,953 sales. By July 2002, RollerCoaster Tycoon had sold over four million copies. Legacy Several sequels would follow RollerCoaster Tycoon and its expansion packs: RollerCoaster Tycoon 2, RollerCoaster Tycoon 3, RollerCoaster Tycoon 3D, RollerCoaster Tycoon 4 Mobile and RollerCoaster Tycoon World. Features found in this game, along with RollerCoaster Tycoon 2, were included in RollerCoaster Tycoon Classic in 2017. Several user-created rollercoasters received media attention after footage of them were posted on various imageboards and social media.
