What It Is

MFD is a single-player franchise sim with deterministic seasons, seeded RNG, stable saves, and a client-side TypeScript engine.

• Draft, develop, extend, trade, and cut players across long-running dynasties.
• Manage cap space, dead money, restructures, extensions, franchise tags, CBA pressure, and owner patience.
• Build coaching staffs, weekly prep, game plans, locker room chemistry, facilities, and scouting departments.
• Watch games through broadcast packages, game flow, play-by-play, standings, records, awards, and media-cycle fallout.
• Preserve careers through Hall of Fame, franchise legends, bloodlines, timelines, scrapbook entries, and GM career history.
• Get coached by Chip — your in-game companion — across the cold open, weekly briefings, route guidance, halftime, recap, press, achievements, and high-stakes moments.

What it is not: a multiplayer service, a card collector, or a server-backed live-ops game. Everything runs in the browser.

Meet Chip

Chip is your franchise's permanent sideline voice. He shows up across 36 distinct poses tied to in-game context — calling plays at halftime, working the phones at the trade deadline, rallying after a touchdown, head-in-hands when the cap projection breaks, fist-bumping when you lock in a decision, proud after an achievement unlock.

Start A Dynasty

1. Open MFD.
2. Pick a franchise and difficulty, or launch the convention demo.
3. Finish setup, advance weeks, and make decisions when the dashboard flags them.
4. Use Save/Load to export portable dynasty backups before switching browsers or machines.

Tech Stack

TypeScript monorepo, pure engine package, React 19 web app, Zustand state, Dexie/IndexedDB saves, Vite build, Vitest coverage, GitHub Pages deploy. Chip's portrait set is generated procedurally from a single rig (scripts/generate-chip-v3-art.cjs), so the cast stays visually consistent across all poses.

Release Notes

See CHANGELOG.md. v1.0.0 ships with save schema v35 and the Sprint 72 deterministic playtest-report cleanup. Recent post-launch polish: the Chip companion has been rebuilt on a unified procedural rig, expanded from 17 → 36 poses, and wired into 11 previously-generic surfaces (training camp, trade deadline, expansion draft, halftime, recap, press, achievement-unlock toast, and more).
