A narrative building videogame based on the management of train-cities (complex societies confined within moving trains), in which the player makes political and technological decisions to progress through the plot. She'll have to ensure the holistic well-being of the population, complete diverse tasks to discover the secrets of the world, the characters, and overcome obstacles found along the way. All of this in a harsh collapsed environment and in a matriarchy-structured society. Questions like gender equality, scarce resources, hostile environment and cooperation will arise to be dealt with.
