| Sawyer has said RollerCoaster Tycoon grew from the abandoned Transport Tycoon 2 project, and that Chris Sawyer's Locomotion (2004), built on the RollerCoaster Tycoon engine, felt like the spiritual successor to the Transport Tycoon games, though it didn't carry the Tycoon name for technical reasons. | biography | Interview |
