It's important to note that "designed" can be interpreted in a few ways:
* Lead developer: While the specific individuals involved in the development of Dunia aren't publicly known, the lead developers at Crytek would be the ones most responsible for the overall design and architecture of the engine.
* Team: The engine was developed by a large team of programmers and engineers at Crytek, so many people contributed to its design.
* Specific components: Some components or features within the engine might have been designed by particular individuals.
Therefore, attributing the "design" to a single person would be inaccurate. It was a collaborative effort by the entire Crytek team.
