The Space Rings and the Twist/Scrambled Eggs rides are in the Gentle Rides and Thrill Rides categories respectively when it should be the other way around, since the former has a high nausea rating while the latter is much less intense.
The 3D Cinema ride/attraction's capacity states that it holds up to 30 guests, but could only technically hold up to 8 guests before declaring it full before showing a film. This is fixed up in the Corkscrew Follies/Added Attractions expansion pack.
In RollerCoaster Tycoon Classic, when the guests board the Merry-Go-Round ride/attraction, none of them are shown riding it (regardless of its occupancy of up to 16 riders), unlike early versions of this game.
The breakdown regarding the station platform's inability to slow down vehicles arriving at the station is misspelled as "Station Breaks Failure". The homophone is corrected in RollerCoaster Tycoon 2 and RollerCoaster Tycoon Classic.
The park award for the scenario's exceptional cleanliness is misspelled as "Tidyest Park Award" in the base game. This is corrected in the Corkscrew Follies Expansion pack and all later games and iterations by replacing the letter "y" with the second "i".
The Merry-Go-Round ride has horses for single riders, but only runs in even numbers of guests riding it out of its 16-guest maximum capacity.
