Urho3D vs GameGuru

The entire engine is open source and makes use of other open source libraries. Source code is licensed under MIT and available on GitHub.

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.

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.

Only use what you need.

Builds are quite fast, aids in rapid development.

Urho3D is written in a modular and super-clean way, so that it can be integrated into the other parts of your game seamlessly.

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).

You can configure rendering pipeline.

There are no lights limits per mesh.

Information on enabling OR support can be found here.

Simplicity and accessibility are the core design goals of FPS Creator Reloaded.

Users share ideas, help, and advice through the official forums. The community also provides a wealth of free assets, and the GameGuru Assets Store sees constant additions.

News and improvements are released on a monthly schedule. Interaction between The Game Creators and project backers is excellent.

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.

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.

Games you publish with GameGuru can be sold without any restrictions or commissions.

An easy 3D editor to create your own maps in seconds with drag-and-drop function.

Awesome friendly GUI, and quite easy to use.

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'.

Uses Lua.

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.

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.

The game engine is optimized for efficient use of memory.
