These lots act as a home for Sims on adventures or visiting the future. There is one base camp in every destination from World Adventures, and each one holds a noticeboard that generates new adventures. The noticeboard also acts a mailbox where sims can submit gems and other items for processing. Explorer NPCs also stay with you at the base camps. Creators using Create a World can set lots to base camp but the lot type serves little purpose in home worlds.
