Yesterday's Tomorrow
A retro-science-fiction roleplaying game about the future as imagined from the past. Characters explore a world of speculative technology, Victorian mysticism, high-stakes action, and romantic adventure, drawing on pulp films and early twentieth-century futurism. Players create characters around four core themes—Action, Science, Mystery, and Romance—and use them to guide dangerous, suspenseful stories involving eccentric inventors, adventurers, occult mysteries, and imagined technologies.
