and RollerCoaster Tycoon 2, the guests, called "peeps", arrive in groups and show variation in gender and age, including children, teenagers and adults. A day/night cycle changes the demographics of the park's peeps; rides at night appeal to teenagers, while the daytime attracts families with children. Peeps can be harmed and injured by crashing vehicles, but will never die as they did in the previous titles, and if placed in water they will swim out. When cars derail from the tracks, they explode after a short period, whereas in the older games, they exploded on contact. Furthermore, a feature was added in which, after a cheat code was entered, people could utilize the Peep Cam from which they could see the park through a peeps' eyes. Parks now have opening and closing times, and the time of day is displayed. Scenery is divided into themes to customize parks, with western-, spooky-, science fiction-, prehistoric-, tropic (Paradise Island)- atlantis- and adventure-themed pieces. Another feature is the ability to import coasters from previous games in the series into RollerCoaster Tycoon 3. The game uses full 3D graphics instead of the isometric viewpoint of the previous games; this means that players can rotate and zoom the view of the park to any degree. However, there is an option to fix the camera's rotation to a preset angle, as in the previous games. 3D land shaping is also available for creating mountains and hills inside the park, as well as the ability to change portions of the land into water. Development Although the core features of Roller Coaster Tycoon 3 are based on the previous games, Chris Sawyer, the developer of the first two games, acted only as a consultant, as the game was instead developed by Frontier Developments, since Sawyer was developing Chris Sawyer's Locomotion at the time. Expansion packs Two expansion packs for RollerCoaster Tycoon 3 were released – Soaked! and Wild!. A bundle, RollerCoaster Tycoon 3 Gold, was also released, including the original game and the Soaked! expansion pack; this was followed by RollerCoaster Tycoon 3 Platinum (Deluxe for the EU version of the game), including both expansion packs and the original game. RollerCoaster Tycoon 3 Platinum is available for Windows and macOS. The game was also published by Aspyr Inc. on the Mac App Store in 2012. Soaked!, the first expansion, allows the player to build water parks, which include
