Chris Sawyer, the creator of the RollerCoaster Tycoon series has also created other games.
In 1994, Sawyer created Transport Tycoon, a game which focused on transporting passangers and goods from one city or factory to another. Over the next two years, a world editor was released, as well as the Windows 9x-compatible Transport Tycoon Deluxe. In 2004, the game was released as open source, and that variant of the game, called OpenTTD, is still being updated, expanded and translated into more than 50 languages.
Chris Sawyer's most famous game to date, RollerCoaster Tycoon was originally intended to be a rollercoaster simulator named White Knuckle. During the development stage, it became a funpark sim game. It was one of the top-selling PC games of 1999. Two expansion packs, Added Attractions/Corkscrew Follies and Loopy Landscapes followed and the game returned to its title of the #1 best selling game by the end of 2000.
RollerCoaster Tycoon 2
The first sequel to RollerCoaster Tycoon. Although it was not initially very well recepted by the critics, who could not see a point in delivering more of the same, RollerCoaster Tycoon 2 is to this day the best-selling game in the franchise. Two expansion packs were released - Wacky Worlds and Time Twister, but Sawyer had no part in their development.

Chris Sawyer's Locomotion
Locomotion was the last game Sawyer worked on for the PC. It's based narrowly on his 1994 Transport Tycoon, but has updated graphics and is fully compatible with newer systems. The scenario editor is built in the game, just like in RollerCoaster Tycoon 2.
Transport Tycoon (iOS/Android)
In 2010, Sawyer returned to gaming development with his new company, 31X Ltd. In 2013, the studio released a game titled simply Transport Tycoon, which utilised the graphics of Locomotion, but with a new interface adapted to smartphones and completely new coding.
