CheatsLike Theme Park, if a player cheats the game makes a point on telling everyone that, but instead of just displaying a pop-up box, the announcer can be heard saying "Warning: a cheat is running the hospital" and "Hospital administrator is cheating", among others.
Custom musicIt's possible to play custom midi files in Theme Hospital's jukebox using the executable sound\midi\hospmidi.exe under the installation directory. Look for more information in the readme file located in the same directory.
DiseasesAccording to producer Mark Webley, originally the game was going to use real ailments and diseases. However, it was pointed out that this would mean dealing with a serious subject, with the potential to offend someone, so the design switched to include the comical diseases.
ReferencesIn the intro, some characters from other Bullfrog games can be spotted; a Horned Reaper from Dungeon Keeper and a Eurocorp Agent from the Syndicate series. A doctor can also be seen playing Dungeon Keeper on his PC.
If these Bullfrog product tie-ins aren't enough, the arcade cabinet placed at the staff room plays no other than Hi-Octane.
