Duality vs S2 engine HD

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#.

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

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.

It can be configured to serialize all data in a text-based format, which has been structurally optimized for version control systems.

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.

It is possible to edit weather conditions (rain, thunders,wind, clouds, night and day cycle) by simply moving some sliders.

Important functions can easily be seen and accessed, making the engine quite user friendly, even for beginners or those who are new to the engine.

S2ENGINE HD rendering power is comparable to more famous engines like Cryengine and UE4.

S2ENGINE HD is integrated with a complete terrain editor that lets you sculpt, paint, add vegetation, and add splines like roads, rivers, fences, etc.

Essential functions are very easy to use and understand.
