When comparing Urho3D vs GameApi, the Slant community recommends Urho3D for most people. In the question“What are the best 3D game engines?” Urho3D is ranked 4th while GameApi is ranked 54th. The most important reason people chose Urho3D is:
The entire engine is open source and makes use of other open source libraries. Source code is licensed under MIT and available on [GitHub](https://github.com/urho3d/Urho3D).
Ranked in these QuestionsQuestion Ranking
Pro Free and fully open source
The entire engine is open source and makes use of other open source libraries. Source code is licensed under MIT and available on GitHub.
Pro Includes a lot of samples
There are a lot of sample projects included with the engine for both C++ and Angelscript. They are mostly very simple applications built to demonstrate the engines capabilities and features.
Pro Fat-free codebase
Only use what you need.
Pro Very high code quality
Urho3D is written in a modular and super-clean way, so that it can be integrated into the other parts of your game seamlessly.
Pro Good documentation
The documentation for Urho3D can be split in two parts: auto-generated from class references and documentation written to cover the various aspects, features and systems of the engine. The written documentation is pretty good. It covers most of the aspects of the engine in clear and understandable English.
Pro In constant active development
Bugs are usually fixed that same day. Core devs are very active on forums. New features are always being worked on. HTML5, DirectX11, and OpenGL3.1 support have recently been added (as of 4/15/15).
Pro Small turnaround times while developing
Builds are quite fast, aids in rapid development.
Pro Does not require an editor to get going
Pro Good 3D level editor
Pro Unofficial Oculus Rift support
Information on enabling OR support can be found here.
There are no lights limits per mesh.
Pro Flexible rendering pipeline
You can configure rendering pipeline.

Pro All combinations of the features are working
In order to enable creation of 100 different kind of games, GameApi features are fully supporting all combinations of the existing features. This allows for huge amount of flexibility. The API carefully documents all dependencies between independent plugin-like modules and allows for combining their features in c++ code.
Pro Selection of 2d and 3d algorithms and techniques that construct opengl vertex arrays
The library is based on constructing opengl vertex arrays for 2d and 3d features including changing mesh colours, attaching textures, building larger worlds from smaller meshes, selection of predefined meshes like spheres, cubes and cones, Model loading from .obj files. Font support, gradient and other 2d bitmap operations, creation of 3d objects from bitmaps, Manipulation of points, lines, faces.
Con The UI can be hard on the eyes
Urho3D's UI could cause eye strain.
Con May be a bit hard to get started
To install Urho3D you need to get the archive from GitHub (be careful to download the master branch) and extract it. After that, you need to compile the engine with CMake. If all the dependencies are installed, then it should be a straightforward process, otherwise you will need to track down and install all the missing dependencies.
For people who don't have much experience with CMake this whole process may seem a bit like magic. For people who do have experience with CMake, the whole installation will be relatively easy.
Con In alpha
GameApi has just recently moved from pre-alpha to alpha status.
