Scenario prohibitions are flags which are set in some scenarios. They initially appeared in Rainbow Valley (RCT 1) in which removal of trees and land modifications was prohibited. Those scenarios are challenging. The scenario with the highest number of prohibition flags set throughout RCT history is Harmonic Hills in Corkscrew Follies/Added Attractions. The RCT2 scenario editor allows to set those flags. Switching between guest numbers and names however, can not be deactivated in the scenario editor. Some trainers however, can.
