core loop

fence an exhibit -> match terrain, foliage, rocks, shelter, and toys to the species -> animals grow happy and breed -> guests visit, spend, and react -> awards and income -> research and adopt more animals

design notes

Zoo Tycoon's core rule is exhibit suitability: each species reports how well its exhibit's terrain mix, foliage, rocks, shelters, toys, and keeper care match its needs, and that suitability drives animal happiness. Guest happiness depends on animal happiness, the species on show, buildings, and scenery, so the two satisfaction meters are chained. Failures are physical: incompatible species in one exhibit kill each other, fences decay, and escaped animals attack guests and staff. Too many complaints about unhappy animals block new adoptions until habitats are fixed.
