Collecting, while not defined in the game, did exist to some extent in The Sims Castaway Stories. In order to survive, Sims could gain resources by collecting various debris across the island, such as metal, wood, grass or bamboo. Sims could also earn food by gathering fruit from different trees or by fishing or spearing fish. A Sim who has collected an insect, may donate it to the Science Lab for money, the rarer the insect, the bigger the amount of money you receive. Collecting is a skill not shown in the skills tab. Instead, it is a special skill only shown in the skill journal.
