My team develops a new game called Archbox, and it uses Irrlicht 1.8 as a graphics engine. There are some certain features:
- Over-Int64! procedural terrain (CPU/GPU realtime, caves allowed)
- Procedural skybox
- Building stuff
- Thermodynamics
- Survival elements
- Dynamic character physics
- Realistic water
- And more to come

If you want to know more about the game or may be can offer some help with its development, let me know either here, or on YouTube, or use email or skype (in any video description).
