Quest & Mission Design

Purpose

Quest types, objective trees, reward structures, and mission flow design for any game genre. Enforces narrative coherence through mandatory lore checks.

When to Use

Trigger: quest design, mission design, objectives, quest types, quest rewards, quest tree, mission flow, side quests, main quest, quest chain, objective design

Prerequisites

• quest-narrative-coherence — MANDATORY. Read and follow the 5-step coherence check before creating ANY quest.
• game-design-fundamentals — core loop and reward system knowledge
• worldbuilding — world context for quest setting

Core Principles

Jonathan Blow: "Every puzzle should feel like a genuine insight, not busywork." Sid Meier: "A game is a series of interesting decisions." Hidetaka Miyazaki: "Quests should reveal the world, not just provide objectives."

1. Every quest must pass the coherence check — no orphan quests, no lore contradictions (see quest-narrative-coherence)
2. Objectives must present meaningful choices — not just "go here, collect that" (Sid Meier)
3. Quest rewards must match the game economy — cross-reference game-economy-design for balance
4. Multi-path solutions — at least 2 ways to complete any significant quest (Jonathan Blow)
5. Quests reveal world — every quest should teach the player something about the world (Miyazaki)
6. Pacing matches the game — quest length and density fit the session cadence from game-design-fundamentals
7. No fetch quests without narrative purpose — if a quest is mechanically simple, it must be narratively rich

Step-by-Step Instructions

1. Run Coherence Check

Follow the 5-step check from quest-narrative-coherence. Load lore, check registry, validate, reference existing content, register.

2. Define Quest Type

Choose from the quest type taxonomy (see below).

3. Design Objective Tree

Map out the objectives, branching paths, and completion conditions.

4. Balance Rewards

Cross-reference game-economy-design for appropriate reward scale.

5. Write Quest Brief

Use the quest template in templates/.

6. Register Quest

Add to quest-registry.md per the coherence clause.

Quest Type Taxonomy

| Type | Description | Example (abstract) | |------|-------------|-------------------| | Main Story | Advances primary narrative arc | "Uncover the truth about [event]" | | Side Quest | Optional, enriches world | "Help [NPC] with [problem]" | | Chain Quest | Multi-step, each unlocks next | "Phase 1 → Phase 2 → Phase 3" | | Branching | Player choice determines outcome | "Side with [A] or [B]" | | Repeatable | Can be done multiple times | "Daily challenge: [task]" | | Discovery | Triggered by exploration | "Find [hidden thing] to unlock" | | Social | Requires other players | "Complete [task] with a group" | | Timed | Must complete within deadline | "Finish before [timer] expires" | | Collection | Gather a set of items/objects | "Find all [N] pieces of [set]" | | Escort/Protect | Keep something safe | "Protect [target] during [event]" |

Objective Tree Structure

Quest: [Name]
├── Objective 1: [Required]
│   ├── Sub-objective 1a: [Required]
│   └── Sub-objective 1b: [Optional bonus]
├── Objective 2: [Choice A OR Choice B]
│   ├── Choice A: [Path with consequence X]
│   └── Choice B: [Path with consequence Y]
└── Objective 3: [Final — depends on choice above]
    ├── Outcome A: [If chose A above]
    └── Outcome B: [If chose B above]

Cross-References

• quest-narrative-coherence — MANDATORY prerequisite
• worldbuilding — world context for quest setting
• game-economy-design — reward balancing
• game-design-fundamentals — core loop integration
• character-design-narrative — NPC involvement
• postgres-game-schema — quest data persistence

Pitfalls & Anti-Patterns

• "Go collect 10 things" — collection quests without narrative justification
• "Orphan quest" — quest that connects to nothing in the world (caught by coherence check)
• "Reward inflation" — quest gives too much, breaking economy
• "One true path" — quest with only one solution removes player agency
• "Lore dump quest" — NPC talks for 5 minutes, player does nothing
• "Invisible prerequisite" — quest requires something the player can't know about

Designer Philosophy

Jonathan Blow (Braid, The Witness): Every quest objective should feel like a genuine insight. If the player is just following a marker, the quest has failed. The best quests make players think, experiment, and discover.

Sid Meier (Civilization): Quests are decisions. "Go kill X" is not a decision. "Choose between helping faction A (gaining their trust but angering B) or helping faction B" IS a decision.

Hidetaka Miyazaki (Dark Souls, Elden Ring): The best quests don't announce themselves. They emerge from exploration, environmental clues, and NPC conversations. The player should feel like they discovered the quest, not that it was assigned.
