The Seam is a pervasive, collaborative fiction game played earnestly. The world it describes is imagined together by its players, one true-life sighting at a time. Sightings are real events players witnessed; making meaning of them is the game.
House rules: avoid real, living people, medical or political claims. "Yes, and" is the correct response.
What is a pervasive game?
A pervasive game is one that escapes the usual boundaries of play. Instead of happening on a board, a screen, or a field, it unfolds inside ordinary life: your streets become the map, your errands become quests, and strangers may be players without knowing it. The "magic circle" that normally separates a game from the world is stretched until the two overlap, so playing changes how you see the places and hours you already inhabit. Some classics: Assassin, Geocaching, The Beast, Perplex City, Humans vs. Zombies, and Pokémon GO.
- Discordianism (1963) — a religion disguised as a joke disguised as a religion, worshipping the goddess of chaos; its Operation Mindfuck seeded playful conspiracy into the culture and is an ancestor of this whole genre.
- The Philip Experiment (1972) — a Toronto parapsychology group invented a fictional ghost, biography and all, then held séances for him. The table rapped back: collective belief in a known fiction producing real experience.
- Ong's Hat (1980s–90s) — the proto-ARG legend of an interdimensional cult in the New Jersey Pine Barrens, seeded across zines and early message boards.
- World Without Oil (2007) — thousands of players lived a fictional oil crisis as if it were real for 32 weeks, documenting how their lives changed; "play it before you live it." Produced with PBS's Independent Lens, and the heart of Jane McGonigal's TED talk on games remaking the world.
- Year Zero (2007) — Nine Inch Nails' dystopian album universe, leaked through USB drives left in concert venue bathrooms, dozens of hidden websites, and images buried in the songs’ own spectrograms.
- Foldit (2008) — mass play doing real science: gamers folding proteins solved a retroviral enzyme structure that had stumped researchers for years, and were credited in the published paper.
- The Jejune Institute (2008) — thousands of San Franciscans were inducted into a fake mystical institute via sidewalk flyers, all in service of urban re-enchantment; the closest ancestor of The Seam. Chronicled in the documentary The Institute and dramatized in the miniseries Dispatches from Elsewhere.
- Cicada 3301 (2012) — the anonymous internet-wide cryptographic mystery that began with this recruitment post; no company behind it, never fully explained.
- QAnon (2017) — never built as a game, but it ran on the same machinery: it "pushes the same buttons that ARGs do, whether by intention or by coincidence," as game designer Adrian Hon wrote in What ARGs Can Teach Us About QAnon. The cautionary tale this genre answers for.
