The second expansion from September 2000, Loopy Landscapes, added further new rides and scenarios, along with the option for all rides to play a selection of new music tracks by Allister Brimble or one of two custom music slots filled by the user's music files. Aside from new scenarios (one being the first real-world park replica, Alton Towers) and rides, it added gameplay changes like signs that can be used as path blockers for all non-staff and the option to give guests 'real' names. The game's first expansion from November 1999 had two titles for different markets: Corkscrew Follies in North America and Added Attractions internationally. The visuals were created by Simon Foster, while the theme music was composed by Allister Brimble. The code was written by Chris Sawyer himself in assembly language with just a small portion of the code interfacing to Windows and DirectX written by Fish UK. The game started development in September 1996, running on an evolution of the Transport Tycoon Deluxe engine, under the name White Knuckle. RollerCoaster Tycoon is an isometric amusement park building game released in March 1999 by Chris Sawyer.
