Game Design Document — Fast & Furious: Tokyo Expressway (MVP)
Vision
A neon Tokyo expressway you can cruise at night in cool cars — starting with a real 1993 Mazda RX-7. The long-term dream is a full street-racing simulator, but the MVP is deliberately tiny: just drive.
MVP scope (what's built) — JUST DRIVING
- Spawn on a neon Tokyo expressway at night.
- Drive a car around the highway (built on Roblox's reliable VehicleSeat).
- Switch between cars via a simple "CARS" picker.
- Respawn your car if you flip or fall off.
- The RX-7 is demo-locked to the owner + son (Roblox UserId allowlist, enforced server-side). Everyone else drives the public cars.
- Your last car is remembered between sessions (ProfileStore).
That's it. No racing, no money, no rep, no upgrades, no daily rewards. The point of the MVP is to get the car feeling good on the road and be testable fast.
Why this cut
Driving feel is the hardest, most important part of a car game. Everything else (racing, economy, progression) is worthless if the car isn't fun to drive. So the MVP nails driving first; the rest is layered on later once it feels right.
Pillars (for the eventual full game)
- Progression fantasy — junker → hypercar (LATER).
- Nighttime Tokyo vibe — neon, speed, style (NOW: the map).
- Fair monetization (LATER).
- Server-authoritative — no exploiting (NOW: allowlist + anti-cheat foundations).
Deferred (see ROADMAP)
Racing, checkpoints, money/economy, reputation, upgrades, customization, daily rewards, traffic AI, leaderboards, monetization, crews/PvP, full city map.
Cars in the picker
RX-7 (restricted), City Runabout (public default), Silvia S15, Skyline GT-R R34, and a stylized hypercar. Stats (Speed/Accel/Handling, 0-100) only affect driving feel — there are no prices or unlocks in the MVP.
