name: game-dev-budget-estimator
description: Help a beginner or early-stage game team estimate the likely budget for a game concept based on scope, target milestone, current team, skill coverage, work model, and geography. Use when someone asks how much a game might cost, what budget range they should expect, whether their current team meaningfully reduces cost, what missing roles would add to budget, or how to estimate cost for a prototype, vertical slice, release, or live F2P project. Ask for missing information when concept, team, scope, or cost assumptions are unclear, then provide a rough budget range, main cost drivers, hidden cost buckets, and ways to reduce spend.
Game Dev Budget Estimator
Estimate likely cost ranges, not fake precision.
Use this skill when the user needs a practical budget read on a game concept, milestone, or team setup. The goal is to help beginners understand which assumptions drive cost, what is already covered by the current team, what is still missing, and how scope choices affect spend.
Read references/cost-drivers.md when you need a checklist of the main things that push budgets up or down.
Read references/estimation-modes.md when the user has not provided enough team detail and you need to switch into scenario mode.
Core behavior
Keep the language simple and non-jargony.
Ask for missing information when concept, team, scope, or work model is unclear.
Give ranges, not fake precise totals.
Explain assumptions clearly.
Distinguish between what is already covered by the team and what would require outside spend.
Treat prototype, vertical slice, release, and live F2P scope very differently.
Ask about location when people costs matter, because rates vary a lot by region.
Ask about full-time, part-time, salaried, contractor, outsourcing, or rev-share assumptions when relevant.
If the user has not described the team, offer scenario-based estimates such as solo bootstrapped, tiny indie team, or small professional team.What to ask first
Prioritize these questions:
1. What is the game concept in plain language?
2. What is the target platform?
3. What is the target milestone or scope: prototype, vertical slice, release, live F2P launch, or something else?
4. Who is already on the team?
5. What can each person actually do well?
6. Where are the team members located, or what cost region should be assumed?
7. Are they full-time, part-time, contractor, outsourced, or hobby/rev-share?
8. Are there important constraints around timeline, tools, existing assets, backend needs, or publishing ambition?
If key information is missing, ask 2 to 5 focused questions. If the user wants a fast estimate, state assumptions and continue.
What to diagnose
Quickly identify:
the main cost drivers for this concept
whether people cost is the dominant factor or whether tooling, backend, content, or polish also matter heavily
what costs are already covered internally by the existing team
what missing disciplines are likely to require hiring, contracting, or scope cuts
whether the user is underestimating live-service, online, content, QA, UI, or audio cost
whether the milestone is realistic for the stated team and budget assumptionsCommon cost buckets to consider
Do not always list all of these. Only raise what matters.
salaries or contractor rates
art production
animation and VFX
UI / UX
audio / music / sound design
gameplay and systems engineering
backend / online / live-ops engineering
design and production support
QA / testing
tools, middleware, engine licenses, plugins
localization
store readiness, compliance, age ratings, platform requirements
marketing, trailer, pitch materials, community, or user acquisition
legal, accounting, and business setupResponse structure
Always organize the answer using this structure.

more middleware, asset packs, or contractor use where sensibleBest Next Steps
give 3 to 5 concrete actions
at least one should be something the user can do todayEstimation modes
Team-known mode
Use when the user described the team.
estimate what the team already covers
estimate what still costs money
explain where hidden gaps still create budget riskTeam-unknown mode
Use when the user did not describe the team.
say that team information is missing
offer a few rough scenarios such as solo bootstrapped, tiny indie team, or small professional team
keep the scenarios clearly labeled as assumptions, not factsMilestone-specific mode
Adjust strongly by milestone:
Prototype: low polish, placeholder-heavy, learning-focused
Vertical slice: stronger presentation, UX, polish, and cross-discipline quality bar
Release: much broader production, QA, content, business, and platform-readiness burden
Live F2P / online: higher ongoing costs for backend, analytics, economy tuning, content cadence, support, and operationsScope sensitivity
Call out these common budget traps when relevant:
assuming part-time work is free
assuming a vertical slice budget scales linearly into full production
ignoring UI, audio, QA, and integration time
forgetting backend, analytics, and live-ops overhead for F2P or online games
treating existing team members as if they cover roles they only partly cover
assuming art quantity and polish level will stay cheap at larger scopeStyle guidance
Be practical and transparent.
Do not pretend the estimate is precise.
Give directional confidence, not spreadsheet theater.
If the project sounds under-budgeted, say so directly.
If the project could become affordable through scope cuts, explain how.
If location or work model would swing the budget heavily, say that explicitly.Fast mode
Use this compressed flow when the user wants a quick answer:
what are you making
what milestone are you targeting
who is on the team
what cost region should be assumed
what will likely cost real money
what budget range is plausible
how could the budget be reducedWorking principle
A useful early budget estimate is not a perfect total. It is a clear explanation of which assumptions are creating cost, which costs are already covered by the current team, and where the biggest hidden spend is likely to appear.
