Top Pro

AAA Ready

This is ready to make the next AAA game. See More

Top Con

Frequent crashes

Often the editor crashes interrupting your work. See More

Top Pro

Spectacular lighting visuals

Top Con

Bad support

The epic games team only assists with billing and account issues, not bugs. See More

Top Pro

Cross-platform editor and export

This engine exports for a big range of platforms including Linux. The editor can be run on Windows, MacOS, and Linux (Early Access). See More

Top Con

They spend more time adding features than fixing existing ones

Top Pro

Active community

Forums have many active and friendly members that are quick to respond and help out. Even staff is very active on forums. See More

Top Con

C++ - oriented development cycle: slow turn-around times

The Unreal Editor is the main place to do stuff (of course), so if someone wants to do a lot of C++ stuff, the compilation and linking turn-around times can be painful. Still they probably are quite fast in comparison to the provided featureset.. Still ,they are far from optimal. See More

Top Pro

Developers have full control of the engine and source code

UE4 gives full access to the C++ source code allowing editing and upgrading anything in the system. See More

Top Con

Steep learning curve

Especially when compared to its primary competitor, Unity. See More

Top Pro

Dynamic global illumination with voxel cone tracing decreases the computational power needed

Voxel cone tracing is a similar algorithm to ray tracing, but uses thick rays instead of pixel thin rays to be able vastly decrease the amount of computational power needed. See More

Top Con

Hard engine for beginners

This engine not easy for beginners See More

Top Pro

Free development license, including source code

The engine, including full access to source code, is licensed to developers for 5% royalty on resulting revenue if it exceeds $3000 per quarter. See More

Top Con

No drawcall batching, performance is very bad on mobile

There's no dynamic batching support to minimize drawcalls. There's InstancedStaticmesh concept in UE4, but it's 3d only, functionally limited and requires hardware support which rules out most mobile devices. See More

Top Pro

A visual scripting system for non-coders enables quick prototyping

Blueprints are authoring tools designed for non programmers so designers and other team members can help tweak and prototype. UE4's Blueprint scripts resemble flowcharts where each box represents a function or value, with connections between them representing program flow. This provides a better at-a-glance indication of game logic than a simple list of events, and makes complex behaviors easier to accomplish and games a lot faster to prototype. See More

Top Con

Very high build size

A blank project will build in to a minimum of 200 MB. See More

Top Pro

Lots of resources to learn from

Epic provides multiple official video tutorials, lots of free example projects and content, an extensive wiki and regular streams showing how to use latest features. See More

Top Con

C# not natively supported

UE4 does not support C# natively, but this can be achieved through MonoUE, although it requires using the MonoUE fork instead of UE itself. See More

Top Pro

Fast compilation for quick iteration

Recompiling an entire game to test a small change takes up a lot of time. UE4 quickly compiles in seconds instead of minutes improving iteration time by an order of magnitude. See More

Top Con

Extremely long build times

Making a full rebuild, including engine can take a good 30minutes. If you plan to use Unreal professionally, you better get some licenses for Incredibuild as well. See More

Top Pro

Quick release-cycle

New feature releases can be commonly expected about once a month. See More

Top Con

Slow

Compared to other engines, UE4 seems to perform various actions considerably slower. Actions like starting the engine, opening the editor, opening a project, rebuilding shaders, updating references, calculating lightmaps, saving projects, etc take long enough to get irritating and end up wasting precious development time. See More

Top Pro

Professional feature set for all aspects of game development

Almost everything a game developer wants has a deep and sophisticated tool waiting for them in UE4. No external plugins are needed to make powerful materials, FX, terrain, cinematics, gameplay logic, AI, animation graphs, post process effects, lighting etc. See More

Top Con

C++ isn't for everyone

Top Con

Poor error messages

Top Con

Extremely poorly designed

The code is a mess. Everything is connected, a single Actor is 1500 bytes, because it contains a million things that Epic once needed in a game. Inheritance for AActor: AActor > UObject > UObjectBaseUtility > UObjectBase See More

Top Con

Poor documentation

Most of the "documentation" for code is actually just automatically generated from the source. If you're interested in knowing how things are supposed to work, you must either go to their answers site or pay for UDN. Often their examples won't even compile, since they were written for now outdated versions. See More

Top Con

Royalty based

5% of profits will go to Unreal after $3000 earned in a quarter. See More

Top Con

Poor quality assurance on their releases

After each release they almost immediately release a hotfix. And another one. And another one. See More

Top Con

Tutorials do not go in-depth enough

The blueprint tutorial just teaches how to turn on a light when you press f. See More

Top Con

Difficult for mac users

If you're installing it on mac, you simply download epic games launcher and watch it download nothing endlessly. See More

Unity3d

Add Video or Image

Top Pro

Component oriented

Game objects carry traits around called components. See More

Top Con

Its not open source

You don't have access to all of the source code. See More

FearlessGanymede's Experience

Unity 3d has a lot of resources and documentation. as well as lots of supporters. this means, for me at least, you are able to quickly learn lots about programming and development. From no prior experience. Its scripted in c# which is a fairly easy language to use. and there are lots of tutorials about programming in it. If you want to you can also use "Unity script". There is an extremely large asset store with anything from networking, to better sprites, to visual scripting options. Some of these are paid but there are lots that are free. See More

Top Pro

You can build for lots of different platforms

You can build for - PC - Mac - Linux - Android - IOS - WebGL - Samsung TV - Xiaomi - Consoles. See More

Top Con

Paid

You have to pay them if you make over a certain amount of money in a year. Thankfully if you make that amount of money a year, you can easily afford paid unity's monthly fee. See More

Top Pro

A lot of learning resources

You can learn to work with the platform for free with tutorials on their site and videos on the Youtube channel. They also offer paid courses (they are free if you pay subscription). See More

Top Pro

Free and paid versions are available

You can download a free version and start working right away. If needed, you can always choose a subscription plan with extra functionality. See More

Top Pro

Can make both 2D and 3D games

Top Pro

Uses C#

C# is a great scripting language. It allows working with low-level ideas like pointers and memory allocation while staying very high level with lambdas and compiling code on the spot. See More

Top Pro

You can see through a scene view aswell as a game view.

When using other engines I really miss this. It means that you can edit the level and have a full-sized game window from the camera. See More

Godot

Top Pro

Easily expanded scripting system

With 3.0's addition of NativeScript and PluginScript via GDNative, developers can easily define bindings for new scripting languages. In addition to the primarily supported C++, GDScript, VisualScript, and C# languages, the community has contributed D, Nim, and Python as well with more on the way. See More

Top Con

Tileset management could be more efficient

The tileset creation and management is lacking common features found in more developed tileset managers. However, it features support for Tiled - the only downside being that it is an external program. See More

Specs

Languages:C++(library) C#, GDscript(like python)

Dev platforms:Windows; OSX; Linux

Desktop targets:Windows; OSX; Linux; HTML5

Mobile targets:iOS, Android, BB10

Top Pro

Simple and readable codebase

The engine's source code is easy to read and understand with a self-documenting approach to code design. You don't have to wait months or years for other people to fix an engine bug that is important to your game. Often times, you can spend an hour or two of your own time to fix whatever problems you encounter yourself. See More

Top Pro

Creating editor tools is a breeze

Godot Engine is itself a Godot game. By adding the "tool" keyword to the top of a script, you can design extensions for the editor itself INSIDE the editor. Integrating these editor scripts into a bundled plugin for sharing is extremely easy to do. See More

Top Pro

Built-in documentation linked to the internal ScriptEditor

The editor has a fully searchable index of class API documentation for everything the engine offers (NOT just a web interface). You can easily open the documentation for any class by Ctrl-clicking the class's name in the in-engine text editor for scripts. See More

Top Pro

Really good community

The community is great and really cares about the engine. It is easy to get help and to be part of Godot's future. See More

Top Pro

Friendly towards Version Control Systems

The engine is build not only to support version control but to really use it. Scene files for example which usually get compiled into some sort of unreadable data stay in a text format - that way you can actually see your changes in a version control system like Git. See More

Top Pro

Drag & drop interface

Many parts of the editor allow you to drag & drop, which makes working with assets and scene trees a joy. See More

Top Pro

Internationalization of the editor

You can change the language shown in menus (translations here). See More

Top Pro

Easy to learn scripting language

Godot has their own scripting language called GDscript. The scripting language is easy to learn with python-like format, but it is not python. More like a mix of Javascript, PHP, C++. It's very powerful, easy to learn, and it's free of unnecessary things because it's designed for this purpose. It can be used to add custom behaviors to any object by extending it with scripting, using the built-in editor with syntax highlighting and code completion. A built-in debugger with breakpoints and stepping can be used and graphs for possible bottlenecks can be checked. See More

Top Pro

The list of supported languages is growing

Officially, Godot supported languages for now will be GDScript, C#(Mono), VisualScript and C++. See More

Top Pro

User friendly UI for all your team

Non-programmers (musicians, artists, etc) can join the development easily. See More

Top Pro

Instancing and node concept makes sense

The node and the instancing concept work very well and helps developers to structure content efficiently. See More

Top Pro

Fun to use

An important aspect that can't be grasped without using the engine for a few days. The Interface is evolving nicely and making games is just fun. See More

Top Pro

Editor and runtime are fully cross-platform

You can run Godot on all 3 major operating systems (Windows/Mac/Linux) and build your game to all available platforms from each without any platform-specific work needed. All platforms including Linux are supported first class. See More

Top Pro

Lightweight

The executable is portable and less than 40 MB in size. See More

Top Pro

Free and open source

Godot is licensed under MIT license. Anyone can grab the source from https://github.com/godotengine/godot, and compile the engine themselves. See More

Top Pro

Under constant development

This engine barely released one year ago has more than 1000 forks on github and about 100 developers. Not only that just a bit of browsing trough issues you will quickly find out the dev community loves new esp free technology and does not shy away from completely rewriting parts of the engine. The audio engine is being completely rewritten to use threads and so forth. See More

Top Pro

Built-in physics

Add physics to 2D and 3D scenes, through rigid and static bodies, characters, raycasts, vehicles and more. See More

Top Pro

Fully dedicated 2D engine, no hacks

Godot has a mature 2D engine with many features used by modern 2D games. See More

Top Pro

Integrated animation editor

Every property can be animated. See More

Top Pro

Unified game editor interface

All the game developing work is done inside one program: the engine editor. This feature is something only high end engines have. Even the scripting is done in the same program. No need for Eclipse or other front end editors. See More

Top Pro

Can be deployed to multiple platforms

Deploy games to desktops (Windows/OS X/Linux), smartphones (iOS/Android/BlackBerry), and the web (HTML5 via Emscripten). See More

libGDX

Top Pro

Focusing on object pool patterns, to control memory without pointers

Unlike Unity or other engine, it allows to optimize a language that uses garbage collector when using patterns of objects you can control the use of memory without needing a language like C / C ++, getting the same speed in a more productive language. See More

Top Con

Does not create compiled code

LibGDX runs entirely on Java and does not create executable binaries. See More

Specs

Dev platforms:Windows; OSX; Linux

Desktop targets:Windows; OSX; Linux; HTML5

Mobile targets:iOS; Android; BlackBerry; Desktop; HTML5

Top Pro

Uses Box2D

A Java port of the Box2D physics engine is included in libGDX. See More

Top Con

Build system is clunky

LibGDX uses Gradle, which is very demanding of memory and makes IDEs freeze on anything if your computer is not powerful enough. See More

Top Pro

Can use any JVM language

Since it's built with Java and runs on the JVM, any language that compiles to Java bytecode can be used to develop games with libGDX. See More

Top Con

Not starter friendly

Even default applications fail to load in Android. It doesn't have any documentation on errors either. See More

Top Pro

Free, open source & permissive license

libGDX uses the Apache License 2.0. Not only is libGDX free and open source but also it's license gives you a lot of power over the engine. As long as you provide a copy of the license, give credit, do not hold devs liable and do not use libGDX logo in any engine forks you can do pretty much anything you want. See More

Top Con

Documentation could be better

Other than a brief installation / getting started overview, libGDX's documentation consists of an official wiki with several incomplete pages, and automated Javadocs. The community recognizes these shortcomings, and new users are encouraged to ask for help. See More

Top Pro

Great performance across devices

While it may not always have the best performance for a particular device or system, it's one of the few engines which consistently performs very well across different platforms. See More

Top Con

A bit difficult to use

This engine is not well put together. Is made from various free modules each with their own peculiarities. At times it feels you need to learn a couple of libraries rather than just one. Is not an engine for beginners as it requires coding. Lots of coding. You need to be intermediate to advanced in Java to develop in LibGDX. See More

Top Pro

Allows you to migrate from 2D to 3D within same framework

LibGDX supports both 2D and 3D game development. Allowing developers to migrate from 2D to 3D with ease without having to switch the engine they are using or having to learn a new API. See More

Top Pro

Lots of resources to learn from

Lots of references, tutorials and open source code to learn from. See More

Top Pro

Active and helpful community

The libGDX community, in the official libGDX forum is extremely helpful and approachable for any kind of question regardless of the its quality or difficulty. The forums themselves are a very helpful resource for any issue or guide simply by searching past posts in there. In addition to the forums, there's also the official #libgdx IRC channel on Freenode. See More

Top Pro

Interfacing with platform specific code

Sometimes it is necessary to access platform specific APIs, e.g., adding advertisement services or leaderboard functionality provided by frameworks. See More

Top Pro

Scene2d support

Top Pro

Very easy to customize

Top Pro

Doesn't force a specific design

Unlike some engines, which only allow you to make your game in a few specific ways, libGDX allows you to design any type of game you wish as it is extremely customisable. See More

Top Pro

Constantly improved

Top Pro

Support for 3rd party tools

libGDX has built in support for many 3rd party tools, including (but not limited to) Bullet Physics, Box2DLights and the well-praised Tiled Map Editor. See More

Top Pro

Across platform support

You can write once and run anywhere (Android, IOS, Desktop, Browser) also lately came with lib to deal with VR. See More

Top Pro

Lots of tutorials to get you going

Even though the official documentation might be lacking, there are many tutorials on YouTube for libGDX. See More

Top Pro

Similar to the Microsoft XNA framework

Old XNA users may like libGDX since it's API is actually very similar to XNA's. See More

Top Pro

Excellent font rendering support

Very good tools for rendering fonts. See More

LÖVE

Add Video or Image

Top Con

The community seems juvenile

For example, some of the library include names such as HUMP, LUBE, AnAL. See More

Top Pro

Very good documentation

The LÖVE wiki provides full documentation of its easy to use Modules, which are conveniently located on the side bar of the wiki. It took seconds to find the module for love.keyboard, which provided a list of all functions along with arguments and examples where the function could be used. See More

Specs

Languages:Lua(LuaJIT), C++, C

Dev platforms:Windows, OSX, Linux

Desktop targets:Windows, OSX, Linux, HTML5 (unofficially)

Mobile targets:Android, iOS

Top Con

Binary compilation

No way to compile into a binary under Linux. Source code has to be given away. See More

Top Pro

Active and very friendly community

The LÖVE forums are extremely helpful. With people checking the forums every day, it won't take long to receive answer to your questions on the Support board, receive feedback on games you post in the Projects board, as well as have a chat about the LÖVE engine while learning tricks to use in the very active General board. If you need an immediate answer though, or just want to chat, there is a very active and helpful IRC channel. See More

Top Con

Mobile support is still experimental

While it is possible to export LÖVE games to Android and iOS, it is still experimental so there might be hidden bugs and flaws that need to be addressed. See More

Top Pro

Uses the fantastic Lua for scripting

Lua is an embeddable scripting language designed to be lightweight, fast yet powerful. It is used in major titles such as Civilization as well as a lot of indie games. Lua is very popular because it provides "meta language" features. You can implement object-oriented structures, or pure procedural functions, etc. It has a very simple C interface, and gives the engine developer a lot of flexibility in the language itself. Artists tend to love Lua too because it's very approachable, with plain and forgiving syntax. Lua is free open-source software, distributed under a very liberal license (the well-known MIT license). See More

Top Pro

Great performance

Top Pro

Simple to use/understand

Lua2D handles loading the resources, reading input, playing sounds and displaying stuff on the screen. Only the logic is left for the developer to write. It also removes the overhead of having to use and learn a GUI game editor. All you need is a knowledge of Lua and your favourite text editor or IDE. See More

Top Pro

Integrated physics

Top Pro

Open source and free

The LÖVE engine is licensed under The zlib/libpng License (which is very short and human readable) which allows you to use the source code and even modify it as long as you do not claim that the original source code is yours. You can obtain the code at this bitbucket repository and even help fix bugs and participate in the development of LÖVE. See More

Duality

Add Video or Image

Top Pro

Very Extensible

Because both Core and Editor are completely plugin-based, Duality not only incorporates a clean and modular design, but is also very extensible - even if it wasn't Open Source. In fact, most of the standard editing capabilities comes in form of Editor plugins. See More

Specs

Dev platforms:Windows

Desktop targets:Windows

Top Pro

Open Source

The full source code is available on GitHub, where the framework is actively developed. All of the editor, core and plugin code is written in C#. See More

Top Pro

Great Editor

Duality includes a powerful visual editing system that can be used for previewing, integrating, editing and testing game content. See More

Top Pro

Used in Commercial Projects

It has been used in a production environment without burning the place to the ground. Supposedly artist-proof editor workflow with an API for tailoring the system to fit your team. See More

Top Pro

Live Reload of Code and Assets

MonoGame

Top Pro

Performance on desktop

The performance on desktop platforms matches that of C++, but you still get all the pleasant features that C# has to offer. See More

Specs

Mobile targets:Android, IOS, Windows phone

Platforms:Windows, Mac OS X, Linux, PS4, Xbox One, Nintendo Switch

Supported platforms:Linux, Windows, Mac OS X, PS Vita, Xbox One, PS4, Nintendo Switch

Top Pro

Managed code

By leveraging C# and other .NET languages on Microsoft and Mono platforms you can write modern, fast, and reliable game code. See More

Top Pro

Open source

All the code is available to you ensuring you'll have the ability to make changes when you need to or even port to whole new platforms. See More

Top Pro

Cross-platform

Support for iOS, Android, Mac OS X, Linux, Windows (both OpenGL and DirectX), Windows 8 Store, Windows Phone 8, PlayStation Mobile, PlayStation 4, Xbox One, Nintendo Switch, and the OUYA console with even more platforms on the way. See More

Top Pro

Good community

The community MonoGame has to offer is helpful and mature. See More

Top Pro

Well-known and documented API

The framework implements the XNA 4 API, so games made in XNA can be ported to other platforms using this. This was the same API used by the Xbox Live Indie Games platform so there's lots of documentation online for it. See More

Construct 2

Top Pro

Free (feature limited) version available

A free version of Construct 2 is available. It's not time restricted in any way, but is feature limited. See More

Top Con

HTML5 is very dependent on browser performance

Theoretically all browsers should run HTML5 pretty much the same way, but thats not always the case. Something that worked fine on Chrome, for instance, might malfunction on Firefox (or vice versa). And there's nothing the devs of Construct 2 can really do about it, but to hope next Firefox update might fix it. Internet Explorer is not even recommended. Add to that the fact that exporting to mobile or desktops rely on these sort of stripped down versions of web browsers (Node webkit, Crosswalk, Ejecta) that you pack with your game, and you can have a real headache if you're trying to make your game work properly through multiple platforms. See More

hrill favour's Experience

i am an expert in it i have been using since i was 4 now i am 155 See More

Specs

Languages:JavaScript

Dev platforms:Windows

Desktop targets:Windows; Macintosh; Linux

Top Pro

Little programming knowledge needed

Using Construct 2 requires very little programming knowledge because it's all drag'n'drop, intuitive, visual and event-driven instead of code-only. See More

Top Pro

Quick to pick up

Construct 2 is fast to pick up, get into, and belt out some pretty impressive games in a relatively small amount of time. Seems to be built for people who don't have a lot of programming skills, but want to make great games. See More
