Parallel IV explores the heroes of the games, the protagonists whom the respective players follow through 1940s L.A., a post-apocalyptic, a Western or other genre worlds. The heroes have no parents or teachers; they must find the rules to follow of their own accord. They hardly have more than one facial expression and only very few character traits which they express in a number of different if almost interchangeable short sentences. They are homunculi, anthropomorphous beings, created by humans. Whoever plays with them has a share in the creator's pride.
