Irrlicht vs S2 engine HD

Many working examples to study and learn. You can easily experiment modifying an example code to grok in full how the engine works. In the beginning of your learning curve, the example code will offer you many useful code snippets.

If you are considering writing your own engine with openGL, you might want to consider Irrlicht instead. It makes many features of any engine worth its salt easy, including events, serialization, nodes, animators, materials, logging, and animation. Bring your own sound and networking.

Especially if you compile it yourself, it can be very light in memory usage.

If you want to start game developing with C++, then Irrlicht is a good candidate since it removes most of the complications in game making in C++. It will let you obtain experience in programming and games at the same time.

This engine supports multiple formats for 3D objects and textures.

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.
