There is no universally best engine for a small indie game. Choose the one that can ship your actual game on its required platforms, fits your team’s existing skills, and stays within your funding and revenue plan. For many teams, Godot is the lowest-cost and most open option; GameMaker can be a straightforward commercial choice for 2D projects; and Unity is the clearest candidate when a project depends on console publishing through a paid plan or an established Unity pipeline. Those are starting hypotheses, not guarantees.
Before committing, build a small vertical slice of your riskiest mechanic and export it to the platform you intend to launch on. Record setup time, iteration friction, missing integrations and build failures. That short experiment is more reliable for your project than a universal ranking.

Start with the decision that can invalidate every other choice: where will the game ship?
Write the release plan before opening an editor. List every platform that is essential, every platform that is merely desirable, and the date by which each must work. Desktop-only, browser, mobile and console releases can lead to very different engine decisions.

Desktop, mobile and web
Godot’s 4.4 FAQ lists Windows, macOS, Linux/BSD, Android, iOS and web as export targets. That is a useful baseline for a game targeting computers, phones or browsers, but verify the documentation for the exact Godot version you will use because export support changes over time: Godot 4.4 FAQ.
#1 Best Overall
GameMaker’s Professional target list includes Windows, macOS, Ubuntu, HTML5, Android, iOS, tvOS and GX Games, according to its current upgrade information. Confirm the current list, required SDKs and any platform-specific review requirements before promising a launch date: GameMaker licence upgrade details.
Unity’s plan page describes publishing to game consoles and Apple Vision Pro as a Pro feature. It also offers a Personal plan for qualifying customers. If your desktop or mobile game may later become a console product, price the plan and porting work before building platform-specific systems: Unity subscription and pricing information.
Consoles
Console development is not just an export checkbox. You may need developer approval, platform-holder agreements, SDK access, certification testing, age ratings, platform-specific input and a porting or technical partner.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesGodot’s 4.4 FAQ says its core team cannot provide an open-source console export because console manufacturers’ licensing terms prevent it. A console plan built around Godot therefore needs a separate feasibility and cost check with an authorized porting route; do not assume that a desktop project can be exported directly to a console.
GameMaker places Xbox, PlayStation and Switch exports under Enterprise rather than Professional. Unity identifies console publishing as a Pro feature. These labels describe engine-plan access, not the complete cost of console development. Budget the platform holder’s requirements, SDKs, hardware, certification fixes and possible external porting separately.
Match the engine to the game you can actually finish
Engine comparisons often turn into claims about which tool is “best” for 2D, 3D, physics or performance. The available official material does not establish a controlled three-way feature, productivity or performance benchmark, so treat those questions as prototype requirements rather than settled rankings.
Rank #2
For a small 2D game
Ask which workflow lets your team build the game’s hardest 2D interaction quickly and repeatably. That might be a procedural level generator, a card-and-status system, a physics-heavy boss, rollback networking, a dialogue tool or a pixel-perfect camera. Build that feature with representative art and input rather than a generic tutorial scene.

Godot is a plausible candidate when you want an open-source engine with desktop, mobile and web exports and the freedom to inspect or modify the engine. Confirm that your required plugins and platform integrations exist for the selected Godot release.
Unity may still fit a 2D game when the team already has Unity production knowledge, needs a particular integration, or expects the project to expand into a broader multi-platform pipeline. Do not select it solely because it can make 3D games; test your own 2D iteration loop.
For a 3D or mixed 2D/3D game
List the rendering features and tools that are non-negotiable: lighting model, shader complexity, animation retargeting, terrain, streaming, physics, cinematics, editor tooling, multiplayer services and target hardware. Then implement the riskiest one in each engine you are seriously considering.

Compare licensing and the full publishing budget
Engine price is only one line in a budget. Include team seats, accounting for plan eligibility, platform services, developer access, SDKs, testing hardware, localization, certification fixes, porting and any middleware or asset licenses.
| Engine and plan | Published cost or threshold | What the cited terms cover | Important qualification |
|---|---|---|---|
| Godot | Free; MIT-licensed | Commercial use is permitted. Creators own and choose the licence for their game content. | When you redistribute Godot binaries, include the required copyright notice and MIT license statement. Console export is not supplied as an open-source core target. |
| Unity Personal | Free for customers with up to USD $200,000 in revenue and funding in 2026 | Use the Personal plan while you remain within the stated eligibility threshold. | Confirm the current terms and regional checkout conditions when your status changes. |
| Unity Pro | USD $2,310 per seat per year, prepaid, or USD $210 per seat per month, according to Unity’s 2026 page | The page lists console publishing and Apple Vision Pro publishing as Pro features. | Regional prices and checkout terms can vary. Pro is required above the USD $200,000 revenue-and-funding threshold stated for Personal. |
| GameMaker Professional | USD $99.99 one-time purchase for commercial publishing on the listed non-console targets | Professional covers the vendor’s listed desktop, web, mobile, tvOS and GX Games targets. | Regional equivalents apply. The help page says non-commercial use is free and commercial use requires Professional. |
| GameMaker Enterprise | USD $79.99 monthly or USD $799.99 yearly | Enterprise covers the vendor’s listed Xbox, PlayStation and Switch exports. | Check current regional pricing and required third-party SDKs and tools before budgeting. |

What Godot’s MIT license means in practice
Godot Engine describes itself as free and open-source software released under the permissive MIT (also called Expat) license. You can sell a game made with it and choose the license for your own game content. If you distribute a binary that includes Godot, preserve the copyright notice and license statement required by the MIT terms. The license does not remove your obligations under console, store, music, font, asset or third-party code licenses.
What changed for Unity’s Runtime Fee
Unity says it canceled the Runtime Fee on September 12, 2024, effective immediately, and says the fee will not apply to games made with Unity 6 or any other Unity version. Do not budget a per-install Runtime Fee based on older articles. You still need to check the plan terms, seat costs and eligibility threshold that apply to your team.
GameMaker’s one-time versus recurring costs
GameMaker’s current help pages distinguish free non-commercial use, a one-time Professional purchase for commercial use on specified targets, and a recurring Enterprise subscription for console exports. A one-time engine license does not make the rest of a console launch one-time: SDK access, hardware, testing and porting can recur throughout production.
Choose a language and workflow your team can sustain
Record what the team already knows, including programming language, source-control habits, editor workflow, debugging and build automation. Familiarity is not a claim that one language is objectively faster; it is a risk estimate for your schedule.
Godot language options
Godot’s 4.4 FAQ lists GDScript, C# and C++ as officially supported languages. It recommends GDScript to people starting with Godot or game development. The same FAQ describes C# support as relatively new and unavailable for web in that documentation version. If a web export or a specific language runtime is essential, test it in the exact Godot release before production: Godot 4.4 language and export FAQ.
Unity and GameMaker language questions
Do not pick an engine from a language label alone. Confirm the current language, scripting, plugin and build requirements in the version you will ship, then have the actual team implement a representative feature. A programmer who knows C# may still lose time learning a new editor, asset pipeline or debugging model; a designer who is productive in a visual workflow may value different trade-offs.
Run a decision prototype before creating production content
Use a time-boxed vertical slice. The goal is not to make a polished demo; it is to expose the risks that could force an engine switch.
- Write the non-negotiables. Specify the launch platforms, minimum hardware, input devices, online requirements, resolution targets, accessibility needs, store requirements and release date.
- Identify the riskiest mechanic. Choose the feature most likely to fail or consume schedule—such as deterministic physics, a large streamed level, a custom editor, multiplayer synchronization or a browser-specific constraint.
- Implement the same slice in each serious candidate. Use equivalent placeholder art, the same input actions and the same acceptance criteria. Avoid polishing one prototype while another remains a tutorial.
- Export early. Build for the intended desktop, phone, browser or console development path as soon as the mechanic works. A successful editor preview is not evidence that the shipping build will work.
- Measure friction. Log setup time, import and compile delays, crash recovery, debugging clarity, source-control conflicts, plugin gaps, build failures and the steps required to reproduce a bug.
- Check the team handoff. Have every role touch the project: code, design, art, audio, QA and release. Note where one person becomes a bottleneck.
- Calculate the switching cost. List scripts, scenes, prefabs or resources, shaders, plugins, save formats and platform-specific code that would need rewriting if you changed engines.
- Make the choice in writing. Record why the selected engine meets the platform, budget and workflow requirements, and define the conditions that would trigger a review.
Use a weighted decision matrix instead of a popularity contest
Give each criterion a weight from 1 to 5 based on its effect on shipping, then score each engine from 1 to 5 using observations from your prototype. Keep “unknown” separate from a low score; an untested feature is a risk to investigate, not proof of failure.
| Criterion | Questions to answer | Suggested evidence |
|---|---|---|
| Required exports | Can the project reach every launch platform through a supported, affordable path? | Successful test build, current plan terms, SDK and developer-access requirements. |
| Riskiest mechanic | Does the hardest system meet your acceptance criteria? | Vertical-slice behavior, frame captures, network or input tests and bug log. |
| Team workflow | Can the whole team edit, review, debug and build the project? | Observed handoffs, source-control test and recovery from a broken build. |
| Budget and terms | Are costs one-time, recurring or tied to revenue and funding? | Official plan pages plus your seat, SDK, hardware and porting budget. |
| Switching risk | What would have to be rewritten if the engine failed? | Inventory of assets, scripts, plugins, save data and platform code. |
Weight platform feasibility and the riskiest mechanic more heavily than a preference for an editor theme or a tutorial’s popularity. A tool that scores well on paper but cannot produce your target build is not a viable choice.

Start with Godot when openness and low fixed cost matter
- Your planned targets fit the documented desktop, mobile and web export path.
- You want a permissive MIT-licensed engine without an engine fee, while accepting the notice requirement for redistributed binaries.
- The team is comfortable learning GDScript, or has a tested C# or C++ plan that fits the target platforms.
- You can solve console publishing through a separate authorized feasibility and porting arrangement if consoles are required.
Do not treat “free” as “zero production cost.” Budget staff time, platform services, testing and any integration work the project needs.
Best Value
Start with GameMaker when a focused commercial 2D release fits its targets
- The game is non-commercial during development or will use Professional for commercial publishing on the listed desktop, web, mobile, tvOS or GX Games targets.
- You can validate your hardest mechanic and export workflow in the exact GameMaker version.
- Console release is either out of scope or the Enterprise subscription and platform path are affordable and confirmed.
Its one-time Professional price can simplify an early commercial budget, but regional pricing and third-party platform requirements still need checking.
Start with Unity when its paid plan and pipeline solve a concrete need
- The team already has Unity production experience or a specific integration that your prototype confirms.
- Console publishing is a requirement and the Pro plan, developer access and porting budget fit the project.
- Expected revenue and funding may exceed USD $200,000, making the Personal eligibility threshold a planning concern.
Unity’s canceled Runtime Fee removes one obsolete cost assumption, not the need to evaluate current seat pricing and plan terms.
Common failure modes and how to recover
Choosing from tutorials instead of the shipping target
Symptom: the team completes a tutorial but has no tested build on the intended platform. Recovery: stop adding content, implement the riskiest mechanic and produce a target-platform build with a clean machine or fresh project checkout.
Discovering console constraints late
Symptom: a desktop prototype works, but console access, export licensing or certification requirements are unclear. Recovery: contact the relevant platform and authorized porting route before committing production assets; re-score the engine with verified costs and lead times.
Ignoring plan eligibility
Symptom: the budget assumes a free plan after revenue or funding changes. Recovery: model the threshold date, seat count and regional price now, and keep a contingency for a plan change.
Treating an untested integration as guaranteed
Symptom: a required SDK, plugin, browser feature or save system is listed as “later.” Recovery: create a minimal integration test and make it a go/no-go criterion for the engine decision.
Underestimating an engine switch
Symptom: the team assumes scenes and scripts can be moved automatically. Recovery: maintain an inventory of engine-specific content and freeze expansion until the prototype proves the current choice. Switching early is usually less disruptive than switching after production dependencies multiply.

A practical decision checklist
- Have we named the must-ship platforms and their deadlines?
- Have we confirmed the engine’s export path, plan and required SDK access for each one?
- Has the actual team built the riskiest mechanic, not just a tutorial scene?
- Have we exported that slice to target hardware or the real browser environment?
- Have we recorded build failures, iteration friction and missing integrations?
- Have we calculated recurring, one-time and revenue-triggered costs?
- Have we preserved required license notices and checked third-party asset terms?
- Have we documented what would trigger an engine review before production locks us in?
Bottom line: choose the project path, then verify it with a build
For a small indie game, the right engine is the one your team can carry from the hardest prototype to a compliant release on the required platform. Godot offers an MIT-licensed, no-engine-fee foundation with documented desktop, mobile and web exports; GameMaker offers a free non-commercial path, a USD $99.99 Professional license for specified commercial targets and a separate Enterprise console plan; Unity offers a free Personal plan within its USD $200,000 revenue-and-funding threshold and a paid Pro route that includes console publishing, with no Runtime Fee under its current policy.
Those facts narrow the decision, but they do not make it for you. Prototype the riskiest mechanic, export it early, price the complete publishing path and select the engine whose constraints your team understands before production begins.
