Theme Park Roller Coaster/Hiring Staff

Mechanics
Mechanics are very useful staff members because they can fix your rides if one breaks down. If a ride dies, however, a mechanic cannot fix it and you will have to delete the ride and make a new one.

Janitors
Janitors are also very useful because, like any janitor, they clean stuff up. They clean litter that people throw on the ground. They clean the various bathrooms around your park. They also clean up stink bombs and puke.

Guards
Guards are the most useless group of people to hire because all they do is patrol the park and carry anyone that sets a stink bomb on the ground out of the park. You don't need to hire one until you have a lot of visitors at your park, and you only have to hire one.

Entertainers
Entertainers are staff members that dress up in funny costumes and dance, juggle, do back flips, or anything to please the visitors. They are good to have because they make your guests happier when they see these live performances.

Researcher
Researchers don't do any work in your park directly, but they can research new rides so that your guests can have new things to ride, to eat, and to do. These helpful scientists walk around your park, looking at things, but their presence in the park doesn't affect anything.
