Repro is about making the decision to parent in a world where everyone has enough and biology is no barrier. All family structures are expected and accepted. At birth, everyone is implanted with a fertility blocker, and if an individual wishes to become a parent, they go to Reproductive Services, or Repro. The final step of the process is an in-person retreat at any of the offices throughout the solar system. Counseling and preparation is provided to confirm the decision to become parents, and then the biology of becoming a parent commences. We find our characters on the train ride to such a retreat at one of the Martian offices of Reproductive Services. Characters include non-partnered people, a monogamous, married couple, and two members of a polyamorous household. The facilitator is a Repro agent and narrator, and also expected to ensure players are having a good time
