Hidden Door is an immersive story game that blends roleplay with fan fiction. Players pick a world, add modifiers that shift the mood and storylines, and create a character. A Narrator then builds the story around their choices, so each playthrough turns out differently and comes with a full cast of characters rather than a fixed script. Collectible cards introduce new adventures, and favorite moments can be shared with friends.
Roleplayers, fan fiction readers and writers are the main audience, along with forever game masters and daydreaming world-builders who want a structure for their ideas. There is also a creator side: authors, filmmakers and other professional creatives with a fanbase can let fans play inside their worlds, and Hidden Door uses their existing works to make that easy. Players who simply want a story without writing every line will find the guided format approachable.
Examples from the game include starting a book club with Dracula, fighting a wyvern on the L train through Brooklyn, or challenging Mr. Darcy to a duel of wits in space. Writers can bring existing work or new ideas and build a playable world in as little as 30 minutes, then explore it alone, share it with friends, or publish it and get paid when others play. Authors with an audience can invite readers into their universe as an interactive extension of the books. Shareable moments help fandoms spread by word of mouth, since players can post their favorite scenes and invite friends into original, offbeat story worlds. Every game plays differently because real choices change what the Narrator builds next.
