A whole Final Fantasy VII arrives already built — then Materia hands you the tools to live your own story inside it.
An original alternate timeline laid over the classic era: the Summons rise to reclaim the Planet, warring against both humanity and the Weapons while Sephiroth’s threat grows in the shadows — and people who would never work together are forced into impossible alliances just to survive.
Nine playable heroes — Cloud, Tifa, Aerith, Barret, Red XIII, Yuffie, Vincent, Cid, and Cait Sith — plus 25 named NPCs from Sephiroth and the Turks to the Shinra board, each with a full bio, tastes, and relationships.
From the Midgar slums to the Northern Crater, the whole Planet is a living map — towns, reactors, ruins, and wilds the story moves you through, each with its own people and dangers.
Mako and Lifestream, Cetra and Calamity, Weapons and Summons, the long shadow of Sephiroth — held true to Final Fantasy VII at every turn, and filled in with real FFVII lore wherever the story needs it.
Every named hero and NPC ships with their own portrait, shown as you meet them and in their bio. Prefer your own vision? Drop in your own art and the engine uses yours instead — built-in by default, overridable any time.
Open the Story Studio right inside the engine and shape the whole world by hand — your character, the premise, every place, and the full cast, canon and invented alike. Set how each one feels about you before a word is written, then save it to a single file and hand it to another player to live your version of the world.
Hundreds of hand-written scenes that come looking for you when the world is ready — a friend pulls you aside, a guarded heart finally cracks open, an enemy forces a reckoning. Tied to the right person, the right place, and the right moment, and drawn from so deep a well you could play for a year and never meet the same one twice.
Earn someone’s devotion and every threshold is marked with a moment that’s unmistakably theirs. Push them the other way and it cuts just as deep — warmth curdles to cold, cold to open hostility, and in real danger a betrayed ally can turn on you.
Every character carries a Bond and a Romance meter that shift in real time as the story earns it — warmth, trust, rivalry, love — and the narrator plays each reaction true to exactly who they are.
Each character has things they love and things they can’t stand. Act in line with a like and their bond ticks up; hit a dislike and it slips — fine nudges on top of the larger shifts your conduct earns.
Meet someone new in play and the engine tracks them in their own panel. Canonize a favorite and they become permanent cast across every future story, with an AI-written bio that persists.
The cast remembers exactly who they’d never work with — Shinra and AVALANCHE, Turk and rebel, beast and corporate — and the engine plays the friction of forced alliance for all it’s worth.
Near-eidetic recall that keeps track of everyone you’ve met and everything you’ve done — no drift, no contradictions, no lost threads — while saving you a fortune in tokens.
Travel matters and geography matters. Wander far and the world keeps its shape — the same streets, the same people, the same history — so the place stays real wherever you go.
A growing Book of the world that fills in as you discover it — people, places, and truths — so the lore is always one click away and always consistent.
Materia never replays the game’s plot. It builds an original story around your character and your choices, with consequences you actually earn — no two playthroughs alike.
From Assisted to Legendary — set how hard the world pushes back, from a guided, forgiving story to a brutal one that makes you earn every step.
Runs on your own AI provider with your own key — Grok-optimized, your rules, your costs. Nothing about your story is locked behind us.
Keep multiple saves, jump back in anytime, and export your playthrough as a clean record of the story you made — yours to keep.
Reach a genuinely safe place in the world and the engine settles into a true safe state on its own — danger lifts and the difficulty eases. A breather woven into the world and triggered by where you are, never a button you press.
The Final Fantasy VII World Engine is coming soon to Materia. Join the Discord to be first through the door when the gods come home.
