Theme Park Tycoon

Start with a gate, a patch of land and thirty thousand dollars. Lay paths, build a carousel, feed people, put in restrooms before anyone has to ask. Every guest is someone: they arrive with a budget and a taste for thrills (or not), get hungry and tired, queue, ride, drop their litter if there's no bin, and tell you exactly what they think. Goals level your park up and unlock the Ferris wheel, the pirate ship, the drop tower and the coaster workshop, where you lay track piece by piece — chain lifts, steep drops, banked turns, vertical loops — test it for real physics and g-forces, and ride it in first person. Buy more land, hire janitors, mechanics and a mascot, and watch the park light up after dark. The rides, stalls, trees and guests are all built in code; the ground, paving, timber and shrubs are Poly Haven scans (CC0) and the skies are photographed.
