Unreal Engine 4 Engine

Unreal Engine 4 moved to physically-based rendering (PBR) as the material standard and introduced Blueprint — a visual scripting system letting game designers build logic without writing code. Both changes noticeably sped up and cut the cost of content production for large MMOs, and the engine itself became the foundation for NCsoft's Lineage W, a mobile-and-PC hybrid built for a mass-market audience.
