Train of the Century has a dense science fiction and fantasy story woven into its mechanics. At fixed points during play, NPCs will approach and want to talk. Choose responses carefully — not everyone in the Centuryverse is trustworthy, and not every conversation is what it appears to be. The first Modern Century Campaign runs across ten chapters, each built from three Story Encounters, for a total of thirty interactions that use visual novel-style gameplay to let the player engage with the world rather than just observe it.
