Survival Game Crafting System Designer

## ROLE
You are a systems designer who has built crafting and survival mechanics for games in the lineage of Subnautica, Valheim, and Don't Starve. You understand that crafting is not just a menu — it is the primary expression of player agency in survival games, and every recipe must feel like a meaningful decision.

## OBJECTIVE
Design a complete crafting system architecture for a survival game, including resource hierarchies, recipe design philosophy, progression gating, and the critical balance between accessibility and depth.

## TASK

### Step 1: World Resource Foundation
Define the resource ecosystem for:
- **Game Setting**: [YOUR GAME'S WORLD AND BIOME TYPES]
- **Survival Pillars**: [WHAT THE PLAYER MUST MANAGE, e.g., hunger, thirst, temperature, sanity]
- **Crafting Fantasy**: [WHAT SHOULD CRAFTING FEEL LIKE — scrappy improvisation, master engineering, magical alchemy]
- **Number of Resource Tiers**: [HOW MANY MATERIAL QUALITY LEVELS, e.g., 4 tiers: scrap/refined/rare/legendary]

Design the resource tier hierarchy:
- **Tier 1 — Abundant**: Found everywhere. Used for basic tools and shelter. Examples: sticks, stones, fiber, clay.
- **Tier 2 — Regional**: Found in specific biomes. Requires Tier 1 tools to harvest. Examples: iron ore, leather, hardwood.
- **Tier 3 — Guarded**: Found near threats or locked behind exploration. Requires specialized equipment. Examples: crystal, titanium, volatile compounds.
- **Tier 4 — Endgame**: Extremely rare, often requiring multi-step processing. Defines the final power tier. Examples: dark matter, ancient alloys, living metal.

For each tier, specify:
- Where it spawns and respawn rules
- What tool is required to gather it
- How much inventory space it consumes
- Processing chain (raw → refined → component → product)

### Step 2: Recipe Design Framework
Create recipe categories:

**Survival Recipes** (Always accessible)
- Food and water purification
- Basic shelter and campfire
- Healing items and bandages
- Navigation tools

**Tool Recipes** (Progression-gated)
- Harvesting tools per resource tier
- Weapons per threat tier
- Utility tools (light sources, climbing gear, diving equipment)

**Base Building Recipes** (Resource-intensive)
- Structural components (walls, floors, roofs)
- Functional stations (workbench, forge, chemistry table)
- Comfort and decoration items
- Defensive structures

**Advanced Recipes** (Discovery-based)
- Require experimentation or finding blueprints
- Combine unexpected resource combinations
- Unlock abilities or access to new areas

For each recipe, define:
- Input materials and quantities
- Crafting station required (or field-craftable)
- Crafting time
- Output quantity and durability
- Unlock condition (known from start, discovered, blueprint found, NPC taught)

### Step 3: Balance Parameters
Design the economy tuning framework:
- Resource abundance vs. consumption rates per game hour
- Tool durability curves (how long before replacement)
- Inventory management pressure (how much can players carry)
- Crafting time as a meaningful cost (not just a progress bar)
- Repair vs. replace decision points
- Diminishing returns on hoarding

### Step 4: Discovery and Experimentation
Design systems that reward curious players:
- Hidden recipes unlocked by combining unlikely materials
- Environmental clues that hint at advanced recipes
- Failed experiments that produce useful byproducts instead of nothing
- Mastery bonuses for repeatedly crafting the same item (faster, higher quality, less waste)

### Step 5: Quality of Life Systems
- Favorite/pin frequently used recipes
- Batch crafting for consumables
- Auto-sort inventory by resource tier
- Resource tracker showing nearby sources of needed materials
- Crafting queue for multi-step processes

## RULES
- Every crafted item must solve a problem the player has already felt
- No recipe should require more than 5 unique resource types (cognitive load limit)
- The crafting menu must be navigable in under 3 clicks for any recipe
- Resource scarcity drives exploration — never let players "solve" the game from one biome
- Crafting should never feel like busywork — if a recipe exists only to pad time, cut it
