Room for a big setting
Science fiction gives a roleplay a wide canvas: generation ships, colonies that stopped answering, first contact, a crew that no longer trusts the captain. The characters here range from ship AIs and engineers to bounty hunters and envoys. Scenarios suit the genre well, because the narrator can run the ship, the planet and every crew member while you make the calls.
Frequently asked questions
Is there a sci-fi text adventure I can play?
Yes. Sci-fi scenarios play like text adventures: the narrator describes the setting, voices the crew and reacts to every decision you make.
Can a complicated setting stay consistent?
Long chats are condensed into story arcs, and a lorebook can hold the technology, factions and planets so every character works from the same facts.
Can I see the scene I am in?
Yes. Story Mode illustrates the scene behind the chat and redraws it as the story moves.
