Black Desert has been under development for several years and Pearl Abyss has state that a completely new game engine was created for the game. This was done in order to meet the technical requirements of a large-scale open world that would hold expansive battles such as castle sieges. By having experienced in-house developers, they boldly made their own engine that allowed them to debug and customize their world more easily. Black Desert is a huge sandbox oriented MMORPG that provides a variety of unique experiences, including strategy-oriented action such as castle sieges and complex battle, and also sophisticated simulation content such as trading, NPC-hiring, and real-estate management. The world of Black Desert was divided into two countries – Calpheon and Valencia. These two factions are head to head in competition for The Black Stone, an essential energy resource. Calpheon is a prosperous, commercial-oriented land, while Valencia holds spiritual values above all else.
