core loop

build paths, rides, and shops -> design coasters and test their ratings -> guests choose rides by intensity preference and budget -> thoughts reveal problems -> adjust prices, staff, and layout -> meet the scenario goal

design notes

RollerCoaster Tycoon makes ride design measurable: every built ride is test-run and rated on excitement, intensity, and nausea, and each guest has a preferred intensity and a nausea tolerance, so the ratings decide who will ride and who gets sick afterward. Guests are individual agents with money, needs, and a stream of readable thoughts, which makes park problems inspectable one guest at a time. Rides lose reliability with age and break down unless mechanics inspect them on a player-set interval. Scenario goals (guest counts and park rating by a deadline) chain 21 base parks. OpenRCT2, a reimplementation of RCT2, carries the systems forward, and Planet Coaster and Parkitect are described as spiritual successors.

uses

Crowd preferences

Guests have money, a preferred ride intensity, a nausea tolerance, and needs, and they report thoughts such as a ride being too intense or a price too high.

core
uses

Customer value choice

Guests compare ride and shop prices with ride value and their remaining cash; overpriced items show up as complaints in guest thoughts.

core
uses

Design performance rating

Each ride is test-run and rated on excitement, intensity, and nausea from its track geometry, speeds, and g-forces; ratings set demand and fair price.

core
uses

Modular assembly

Coasters are built track piece by piece on a tile grid, choosing direction, height, steepness, and elements such as loops and corkscrews.

core
uses

Wear and breakdown

Ride reliability decays with use and age; breakdown chance rises as reliability falls, and mechanics inspect and repair on a set interval.

core
uses

Advertising and awareness

The marketing panel runs time-limited paid campaigns, such as park or ride advertising and free-entry or half-price vouchers, that raise guest arrivals or demand for a chosen ride or stall while they last.

supporting
uses

Agent inspection

Clicking a guest shows cash, needs, thoughts, and ride history.

supporting
uses

Agent pathfinding

Guests navigate the path network and can get lost in mazes of paths.

supporting
uses

Decoration and beauty

Scenery and trees improve guest views and ride appeal.

uses

Loans and debt

Parks start with a loan, such as $50,000 in Mega Park.

supporting
uses

Needs decay

Guests get hungry, thirsty, tired, and need toilets during a visit.

supporting
uses

Scenario objectives

Each of 21 base scenarios sets a goal such as a guest count with a minimum park rating by a deadline; completing one unlocks the next.

supporting
uses

Service queues

Guests wait in ride queues and leave long lines unhappy.

supporting
uses

Staff hiring and rosters

Handymen sweep, empty bins, and mow; mechanics fix rides; security guards prevent vandalism; entertainers cheer guests.

supporting
uses

Tech tree

Paid research unlocks new rides and improvements over time.

supporting
uses

Terraforming

Land can be raised and lowered and water added to fit rides and add appeal.

supporting
uses

Track laying

Coaster track is built piece by piece on the tile grid by direction, height, steepness, and elements such as loops and corkscrews, and the result is rated by test run.
