Every property can be animated.
Ranked in these QuestionsQuestion Ranking
Pro Integrated animation editor
Every property can be animated.
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.
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).
Pro Fully dedicated 2D engine, no hacks
Godot has a mature 2D engine with many features used by modern 2D games.
Pro Built-in physics
Add physics to 2D and 3D scenes, through rigid and static bodies, characters, raycasts, vehicles and more.
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.
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.
The executable is portable and less than 40 MB in size.
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.
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.
Pro Easy to learn scripting language
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.
Pro The list of supported languages is growing
Officially, Godot supported languages for now will be GDScript, C#(Mono), VisualScript and C++.
Pro Instancing and node concept makes sense
The node and the instancing concept work very well and helps developers to structure content efficiently.
Pro User friendly UI for all your team
Non-programmers (musicians, artists, etc) can join the development easily.
Pro Internationalization of the editor
You can change the language shown in menus. Godot translations: https://hosted.weblate.org/projects/godot-engine/godot/
Pro Drag & drop interface
Many parts of the editor allow you to drag & drop, which makes working with assets and scene trees a joy.
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.
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.
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.
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.
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.
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.
Pro Scene Based editing
Godot gives you the ability to create scenes to make your life easier, with reusable objects and things you want to incorporate in your games. This makes the game making processvery streamlined and organized.
Pro Great tech support and friendly community
A growing community that is always helpful with dev response times averaging less then 24 hours. Often less than 12.
Pro Comprehensive WYSIWYG editor
Skyline provides a straightforward drag and drop development environment that can be customized to suit individual preferences. Playing the game and animating the scene can be done from within the editor at any time.
Future versions will allow extending editor's functionality with plugins and offer an official way of trading custom plugins.
Pro Highly affordable licensing
Skyline's commercial edition costs just £40, has no royalties or earning limitations and includes 2 activations per license purchase and a year of free updates.
Pro Runs well on lower end machines
Skyline can be run on a machine with 2GHz Dual Core CPU, 2GB of RAM and Nvidia's 9800 GT (or equivalent) GPU. While, obviously, higher specs are recommended, it's reasonable to expect around 60fps on small scenes with these specs.
Pro Excellent terrain editor
The Terrain editor is easy to use and will include features such as hole cutting.
There is a differed lighting render for internal scenes, which makes creating multi light and beautiful/atmospheric scenes so much easier.
All the tools for the terrain are in one place such as placing road/paths, vegetation, billboards, and the settings are easy to locate and change.
Planned features include:
Hole cutting in terrain and
Pro Low learning curve
Making a game in the current top engines is hard work, making something small and basic in Skyline is not. Easy to learn drag an drop model placement and editing supplemented with easy to follow video's on forum make the process straightforward.
Pro Full global illumination
Including image based lighting.
Pro Has a free version
A free version that's limited to non-commercial usage and lacks a few features is available.
Pro Impressive water render
Rendering of a water plane looks fantastic and is easily edited for different effects.
The schematic editor is designed to make it easier for non-programmers to create games.
Pro Asset store
Not much in it at the moment but is starting to grow and will continue to grow with an increase of users.
Pro Constant development and regular updates
There are many additions to the engine that are on the road map such as multi threading and tree physics.
The feature list is constantly evolving with each user request and idea put forth.
Pro Support for custom editors
Skyline has a custom editor that gives the user of making their own tools for use directly in the editor to develop their games. All the editors are made using the Qt Designer and programmed in lua inside the engine itself.
Pro OSVR support announced
Open-Source Virtual Reality support is in development.
Pro More editor's
Weapon Class Editor.
Advanced Mesh Editor.
Environment Editor (volumetric clouds and day night cycle, lightening, ocean settings, height fog).
Pro Lots of learning resources
The documentation is been rewritten and follows a structure like a course.
Introduction to > Level designer with examples > Artists
There is also video tutorials, video examples and video tutorial series been produced.
There are user created demo scenes, examples and more.
Pro Visual GUI/HUD Dditor
Making HUDs and GUIs has never been easier
Pro PBR Workflow
Full PBR workflow, your not stuck to Secular or Metallic it has both
Pro One on one private support with engine developers
Can contact the Skyline developers and they will always respond and help as fast as they can.
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.
Con No built-in way to import atlases
Godot does not have an easy and automatic way to import atlases created by other tools. However, there are plugins that can be used to import atlases from other engines.
Con C++ Engine API not very friendly
The base C++ code from Godot is not documented, it's hard to set it up, to compile and hard to extend, it could use better programming standards.
Con Very bad documentation
The documentation is poorly written, and has very few examples of real application and even fewer design guidelines about how to program a game in the engine.
Con 2DPhysics is weak compared to Box2d
Box2d has much more features.
Con NoAdmob or other AdNetwork support
Godot has no native support for implementing advertisements into your game.
Con Difficult to optimize
Godot has an OOP architecture. Everything is an object internally and data is spread among many classes, thus it's difficult to optimize (i.e. not cache friendly, difficuly to vectorize or paralellize, etc).
Read about "Data Oriented Design" for more info about the problems and solutions.
Con OSX app is a mess
Instead of one contained folder/file with an icon per normal it is a mess of files which is not at all suitable or distributable without further work after every compilation.
Con Hard for a Unity user
Coming from a Unity background, Godot engine is hard.
Con No C++ SDK
Con Small community
There is a small but helpful community that are constantly creating video tutorials and one member is creating a FREE ebook to make the transition to the engine simpler.
Con Currently limited to targeting PC
Mobile targets are planned.
Con Still in beta
Not all features are fully implemented yet.
Con Lacks occlusion culling and lightmapping
This is been added in a future update, however a date of this update hasn't been given yet.
Con Free Version currently not available/severely limited when available.
The free version has massive amounts of features functionality removed, including the ability to compile anything standalone.
The free version is currently (as of November 2017) not available until the next major release.
Note: some of what is below is open to change, this is the coming set of changes.
The price will be jumping from $40 to £99.99 ($132.32) for the lowest tier able to build a standalone. This tier will not be able to remove the engine splash screen.
The next tier will be £199.99 ($264.66).
