When comparing libGDX vs GameGuru, the Slant community recommends libGDX for most people. In the question“What are the best 3D game engines?” libGDX is ranked 6th while GameGuru is ranked 30th. The most important reason people chose libGDX is:
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.
Ranked in these QuestionsQuestion Ranking
Pro Great performance across devices
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.
Pro Lots of resources to learn from
Lots of references, tutorials and open source code to learn from.
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.
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.
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.
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.
Pro Scene2d support
Pro Very easy to customize
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.
Pro Constantly improved
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.
Pro Uses Box2D
A Java port of the Box2D physics engine is included in libGDX.
Pro Across platform support
You can write once and run anywhere (Android, IOS, Desktop, Browser) also lately came with lib to deal with VR.
Pro Lots of tutorials to get you going
Even though the official documentation might be lacking, there are many tutorials on YouTube for libGDX.
Pro Excellent font rendering support
Very good tools for rendering fonts.
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.
Pro Similar to the Microsoft XNA framework
Old XNA users may like libGDX since it's API is actually very similar to XNA's.
Pro Designed for ease of use
Simplicity and accessibility are the core design goals of FPS Creator Reloaded.
Pro Continuous development and updates
News and improvements are released on a monthly schedule. Interaction between The Game Creators and project backers is excellent.
Pro Feature priorities are chosen by the community
The Game Creators team frequent the forums and ask the community for feeback and suggestions both there and via an open poll on the website. They have a great history of reading suggestions, viewing screenshots, and generally working with the community.
Pro Awesome tech support
Pro Easy to use your own custom assets
Easily import your own 3D models with the built-in importer and create custom characters with the Character creator. Custom weapons are much more difficult, though.
Pro Massive community of users
The gamer creator forums have a large number of users, developing games, making models for sale and to give away for other users. They answer questions, help each other with problems in their games, and can make using this software so much more fun and easy.
Pro Friendly GUI
Awesome friendly GUI, and quite easy to use.
Pro Easy to use editor
An easy 3D editor to create your own maps in seconds with drag-and-drop function.
Pro Royalty free
Games you publish with GameGuru can be sold without any restrictions or commissions.
Pro Building editor
Currently in development but already looking very good! Easily create big and customized buildings with default building blocks and share them with others.
Also very easy to use in the designer: The buildings are treated like entities but still directly available in the 'building editor mode'.
Pro Powerful scripting language
Pro Large asset store
A store where you can buy various assets for your games like sounds, 3D models, weapons... Very good prices and a lot of assets are even free.
Pro Optimised engine for editor
The game engine is optimized for efficient use of memory.
Con Not starter friendly
Even default applications fail to load in Android. It doesn't have any documentation on errors either.
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.
Con Does not create compiled code
LibGDX runs entirely on Java and does not create executable binaries.
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.
Con Currently in beta
FPSCR is currently a beta product with features potentially important to a specific project still in the roadmap. Obviously this is expected of a beta product, and new features are constantly being added, but should be taken into consideration when choosing a game engine for a game right now. To see what's currently implemented, being implemented and in the roadmap go here.
Everything takes ages..feels like Unreal 4
Con Windows only
There is only one supported platform. No macOS/Linux or mobile.
Con Lack of user-interface
Although you can customize a lot, the user-interface does not show that. But plans are in place to improve this with some front facing GUI into the LUA scripts so you don't need to code as much.
