# Six-Month MVP Definition
|
||||
|
||||
## Purpose
|
||||
|
||||
The six-month MVP is the smallest playable proof that Agrarian is more than an
|
||||
Unreal template and more than a terrain experiment. It must show the beginning
|
||||
of the long-term game: a player enters a real place, struggles to survive,
|
||||
improves their odds through gathering/crafting/fire/shelter, and can return to
|
||||
some preserved progress.
|
||||
|
||||
The MVP is not a public launch, not the full economy, and not the full
|
||||
Earth-scale world. It is an investor/internal/closed-test build that proves the
|
||||
foundation is worth expanding.
|
||||
|
||||
## MVP Statement
|
||||
|
||||
The six-month MVP qualifies when a small test group can launch a Windows build,
|
||||
enter the Ground Zero map, select a basic realistic character, survive a
|
||||
compressed day/night cycle, interact with a real 1 km x 1 km terrain tile,
|
||||
gather resources, drink water, craft primitive tools, make or use fire, build or
|
||||
use primitive shelter, experience meaningful survival failure, and return after
|
||||
a restart with core world progress preserved.
|
||||
|
||||
## Target Test Audience
|
||||
|
||||
Primary audience:
|
||||
|
||||
- internal development testing;
|
||||
- investor/demo review;
|
||||
- a small closed-test group once the build is stable.
|
||||
|
||||
Target player count:
|
||||
|
||||
- minimum proof: 2 players connected to the same server;
|
||||
- target closed-test smoke group: 4 players on one server;
|
||||
- stretch test: 8 players if the dedicated/listen server path is stable.
|
||||
|
||||
The MVP should not be judged by MMO population, open-world scale, or long-term
|
||||
economy concurrency.
|
||||
|
||||
## Required MVP Pillars
|
||||
|
||||
### Startup And Entry
|
||||
|
||||
Required:
|
||||
|
||||
- Agrarian Studio splash/startup identity appears;
|
||||
- required Unreal/Epic attribution and copyright/demo notice are present;
|
||||
- the motto `What survives after you are gone?` appears in the startup flow;
|
||||
- the player reaches a simple character-selection landing page;
|
||||
- the player can choose a realistic young adult male or female character option
|
||||
with average proportions, even if final character art is still placeholder;
|
||||
- the player enters the Ground Zero map.
|
||||
|
||||
Excluded:
|
||||
|
||||
- full character creator;
|
||||
- polished cinematic intro;
|
||||
- account creation flow;
|
||||
- Steam/Epic entitlement flow.
|
||||
|
||||
### Ground Zero Map
|
||||
|
||||
Required:
|
||||
|
||||
- the default playable map is the Ground Zero 1 km x 1 km real terrain tile;
|
||||
- terrain scale is verified as 1 km x 1 km;
|
||||
- the tile has source/generation metadata;
|
||||
- Ground Zero tile package lookup/download/cache proof exists through the tile
|
||||
server;
|
||||
- water, slope, shoreline/coastal handling, and immediate resources are good
|
||||
enough to support the survival loop;
|
||||
- map boundaries or soft limits prevent players from treating missing
|
||||
neighboring tiles as broken content.
|
||||
|
||||
Acceptable first-pass biome/resource accuracy:
|
||||
|
||||
- biome and resource placement must be believable for the Ground Zero region;
|
||||
- wood, stone, fiber, water, rabbit/meat/hide, and basic forage/medicine
|
||||
placeholders may be approximate;
|
||||
- exact vegetation species, exact abundance, and final ecological simulation are
|
||||
not required;
|
||||
- resource density can be tuned for playability as long as the result still
|
||||
feels regionally plausible;
|
||||
- all approximation should be documented when it matters to future terrain or
|
||||
biome passes.
|
||||
|
||||
Excluded:
|
||||
|
||||
- full Earth-scale streaming;
|
||||
- multiple production-ready regions;
|
||||
- perfect hydrography, roads, land-cover, or vegetation classification;
|
||||
- final ocean/bathymetry simulation;
|
||||
- final World Partition streaming budget.
|
||||
|
||||
### Survival Loop
|
||||
|
||||
Required:
|
||||
|
||||
- hunger, thirst, stamina, health, body temperature, and injury are represented;
|
||||
- hunger, thirst, cold/exposure, and injury/damage can threaten survival;
|
||||
- the player can gather primitive resources by hand;
|
||||
- the player can drink or collect water;
|
||||
- the player can craft at least one useful primitive tool;
|
||||
- the player can craft or use fire;
|
||||
- the player can build or use primitive shelter;
|
||||
- weather and time affect survival pressure;
|
||||
- death or another meaningful failure path works;
|
||||
- early play is difficult but learnable.
|
||||
|
||||
Excluded:
|
||||
|
||||
- full disease system;
|
||||
- full medicine system;
|
||||
- complete cooking and food preservation;
|
||||
- full corpse/backpack/inheritance loop;
|
||||
- advanced combat.
|
||||
|
||||
### Time And Weather
|
||||
|
||||
Required:
|
||||
|
||||
- default gameplay calendar remains `4 real hours = 1 in-game day`;
|
||||
- server owns time and replicates it;
|
||||
- day/night presentation should mimic the Ground Zero region as the system
|
||||
matures;
|
||||
- weather states affect survival pressure;
|
||||
- deterministic fallback weather exists if live weather is not ready.
|
||||
|
||||
Excluded:
|
||||
|
||||
- complete sunrise/sunset astronomy accuracy;
|
||||
- full live weather provider integration if not stable;
|
||||
- crop/livestock/aging timelines beyond documented design direction.
|
||||
|
||||
### Multiplayer
|
||||
|
||||
Required:
|
||||
|
||||
- at least two players can join the same session for a smoke test;
|
||||
- player stats, inventory, time, weather, resources, build pieces, fire/shelter,
|
||||
and relevant world state replicate well enough to test together;
|
||||
- server authority is maintained for critical gameplay actions;
|
||||
- missing tile behavior is defined.
|
||||
|
||||
Excluded:
|
||||
|
||||
- open matchmaking;
|
||||
- polished dedicated-server deployment portal;
|
||||
- MMO-scale population;
|
||||
- full reconnect UX beyond the persistence smoke target.
|
||||
|
||||
### Persistence
|
||||
|
||||
Required:
|
||||
|
||||
- core placed shelter/fire/build progress can survive restart where implemented;
|
||||
- player/world save data uses versioned records where practical;
|
||||
- active Ground Zero tile ID/package version are part of persistence design;
|
||||
- manual/admin save path exists;
|
||||
- persistence limitations are documented.
|
||||
|
||||
Target for MVP acceptance:
|
||||
|
||||
- a test can gather/craft/place, save, restart, and confirm the important
|
||||
player/world state still exists.
|
||||
|
||||
Excluded:
|
||||
|
||||
- complete account identity system;
|
||||
- complete database-backed persistence service;
|
||||
- long-term migration tooling for every future save shape;
|
||||
- full economy ledger implementation.
|
||||
|
||||
### UI And UX
|
||||
|
||||
Required:
|
||||
|
||||
- basic survival HUD or debug/HUD equivalent shows critical stats clearly enough
|
||||
to test;
|
||||
- interaction prompts exist or the test flow otherwise makes interactions clear;
|
||||
- inventory and crafting can be tested without hidden developer-only knowledge;
|
||||
- death/failure state is understandable enough for testers;
|
||||
- UI scales acceptably on common desktop resolutions.
|
||||
|
||||
Excluded:
|
||||
|
||||
- final HUD art;
|
||||
- final accessibility pass;
|
||||

|
||||
- known startup/rendering fallback path is documented;
|
||||
- tile endpoint used by the build is documented;
|
||||
- backup and restore expectations are documented;
|
||||
- critical known issues are tracked before investor/closed-test sharing.
|
||||
|
||||
Excluded:

- store-ready Steam/Epic deployment;
|
||||
- installer polish;
|
||||
- crash telemetry service if not yet selected;
|
||||

|
||||
|
||||

|
||||
- public anti-cheat and moderation suite.
|
||||
|
||||
## Acceptance Checklist
|
||||
|
||||
The MVP can be called ready for the six-month target when:
|
||||
|
||||
- packaged Windows build launches;
|
||||
- startup flow reaches character selection;
|
||||
- player enters Ground Zero;
|
||||
- two-player smoke test connects;
|
||||
- one player can gather, drink, craft, make/use fire, and use shelter;
|
||||
- one meaningful survival failure path works;
|
||||
- one full compressed day/night survival test passes or has documented known
|
||||
gaps;
|
||||
- weather/time survival pressure works at a basic level;
|
||||
- core world progress can survive restart for the implemented persistence scope;
|
||||
- Ground Zero tile delivery proof remains valid;
|
||||
- no critical crash blocks the first 30 minutes of testing;
|
||||
- known missing features are listed as exclusions or future roadmap items.
|
||||
|
||||
## What Success Looks Like
|
||||
|
||||
The MVP succeeds if a tester can say:
|
||||
|
||||
- this is clearly Agrarian, not a template;
|
||||
- the real terrain direction is visible;
|
||||
- survival feels grounded and a little difficult;
|
||||
- tools, fire, shelter, and knowledge make survival easier;
|
||||
- the world remembers enough to see the persistence direction;
|
||||
- the next roadmap phases are credible.
|
||||
|
||||
The MVP fails if it relies on explanation instead of play, if basic survival
|
||||
cannot be completed, if the build cannot launch, or if the project tries to
|
||||
include long-term systems before the survival foundation is stable.
