Game Design Prompt Templates
AI prompt templates for game design. Develop game mechanics, narratives, and experiences.
Overview
Game design prompts help you create mechanics, systems, and experiences that players want to engage with. Whether you're designing board games, video games, or tabletop RPGs, these templates push you to think about player motivation, balance, and fun. Use them when you're starting a new project, when a mechanic isn't working, or when you need to generate ideas quickly during development.
Best Practices
Start with the feeling you want players to have, then work backward to mechanics that create it.
Every system should give players interesting decisions. If there's always a correct answer, the system is broken.
Playtest with people who will be honest with you. Your mom saying it's great doesn't count.
Steal shamelessly from other games, then combine elements in new ways. Innovation usually comes from intersection.
Cut anything players skip or ignore. If they're not engaging with it, it shouldn't be there.
Prompt Templates
1. Core Loop Designer
Design a core gameplay loop for a [GENRE] game where the player's main fantasy is [PLAYER FANTASY]. The loop should have: 1) A primary action the player repeats often, 2) A reward that makes the action feel meaningful, 3) A way the reward feeds back into making the action better or more interesting, 4) A failure state that teaches without punishing too harshly, 5) How the loop evolves over a [PLAYTIME] session.
Genre: Roguelike deckbuilder. Player fantasy: Being a clever tactician who outsmarts impossible odds. Playtime: 30-minute runs.
PRIMARY ACTION: Playing cards from hand to defeat enemies in turn-based combat. Each turn is a puzzle of 'how do I maximize damage while surviving?' REWARD: Defeating enemies gives card draft choices. Pick one of three cards to add to your deck. Meaningful because you're building toward combos you've envisioned...
When you're establishing the fundamental rhythm of your game
- •The best loops feel different at hour 1 than hour 20 while using the same basic mechanics
- •Test your loop with placeholder art. If it's not fun without polish, polish won't save it.
2. Mechanic Problem Solver
My game has this mechanic that isn't working: [DESCRIBE MECHANIC AND PROBLEM]. Players are [OBSERVED BEHAVIOR]. I want them to [DESIRED BEHAVIOR]. The game is [BRIEF GAME DESCRIPTION]. Give me: 1) Diagnosis of why it's not working, 2) 3 different solutions ranging from small tweak to major overhaul, 3) Potential side effects of each solution, 4) How to test which solution works.
Mechanic: Players can trade resources with each other. Problem: Nobody trades. They hoard everything even when trading would help everyone. Observed behavior: Players wait until they can win alone rather than cooperate. Desired: Trading becomes a natural, frequent part of play. Game: Economic strategy board game, 90 minutes.
DIAGNOSIS: Trading has no urgency and high risk. Why trade when someone might use those resources to beat you? The reward is theoretical, the loss is immediate. SOLUTION 1 (Small): Add decay. Resources lose value each round. Trading becomes 'use it or lose it.'...
When playtesting reveals a mechanic that players ignore or exploit in unfun ways
- •Watch what players do, not what they say. They'll tell you it's fun while clearly not having fun.
- •The smallest change that fixes the problem is usually the right one
3. Difficulty Curve Architect
Design a difficulty progression for a [GENRE] game that's [LENGTH] long. The player starts with [STARTING ABILITIES] and ends with [ENDING ABILITIES]. Create: 1) 5-7 difficulty stages with what changes at each, 2) How new mechanics are introduced (not all at once), 3) Intentional 'rest areas' where difficulty plateaus, 4) The spike moment that tests everything they've learned, 5) How the ending feels earned rather than anticlimactic.
Genre: Metroidvania platformer. Length: 12 hours. Starting abilities: Jump and basic attack. Ending abilities: Double jump, dash, wall climb, three attack types, and a special meter.
STAGE 1 (Hour 1-2): Basic platforming. Enemies telegraph attacks slowly. Goal: Master timing and spacing. Only ability: jump and basic attack. REST AFTER: First boss is a skill check, not a wall. STAGE 2 (Hour 2-4): Introduce dash. Level design now requires dash timing...
When pacing player progression and challenge throughout a longer game
- •Difficulty should ramp like stairs, not a slope. Flat periods let players consolidate skills.
- •The hardest moment shouldn't be the final boss. Give players a victory lap after the peak.
4. Emergent Narrative Generator
Design a system that generates player-driven stories in a [GENRE] game about [CORE THEME]. The system should create: 1) Situations that force meaningful choices, 2) Consequences that ripple forward unpredictably, 3) Characters/factions that remember player actions, 4) Environmental storytelling that changes based on player behavior, 5) An ending that reflects the journey, not just the final choice.
Genre: Colony survival sim. Core theme: What compromises are acceptable when survival is at stake?
MEANINGFUL CHOICES: Resource scarcity forces impossible decisions. A refugee caravan arrives when you barely have enough food. Take them in (strain resources, gain workers, moral boost) or turn them away (immediate stability, long-term guilt reflected in colonist mood). RIPPLE EFFECTS: Those refugees remember. If they survive elsewhere, they may return as traders or raiders...
When you want players to generate their own stories through systems rather than scripted events
- •The best emergent stories come from systems interacting in ways you didn't fully anticipate
- •Give players tools to share their stories. Screenshots, replays, export functions.
Common Mistakes to Avoid
Designing for yourself instead of your audience. What you find fun after 100 hours of development isn't what new players find fun after 10 minutes.
Adding complexity without depth. More rules don't mean more interesting decisions. Often they mean more confusion.
Ignoring the moments between 'fun.' Menu navigation, loading, downtime all shape how the game feels. Polish everything players touch.
