Thinking of maybe writing a story based in the blade runner universe. Honestly, im surprised no one has done it before as we are already given clear examples of replicant being made for the purpose of sex. Luv (a replicant) even mentions it when she is talking to a client in the newer movie. Another interesting aspect is implanted memories and made to order models. It would be a cool plot point if characters were to wonder if they were really that persons wife of husband or just a product made to think that.
