Brendan Greene, known for creating PUBG, is working on a new project called Prologue, which tests innovative terrain generation technology for his larger vision, Project Artemis. Prologue aims to refine machine learning algorithms that can produce over 4 billion unique map configurations. Greene acknowledges past leadership challenges but credits CTO Laurent Gorga for fostering a collaborative development approach. He estimates that achieving Project Artemis could take up to a decade and emphasizes the importance of Prologue's commercial success for securing resources. Greene envisions Project Artemis as a vast, player-driven universe, inspired by games like Minecraft and No Man's Sky, with a world measuring 10,000 square kilometers. He aims to create an environment where players can craft diverse experiences and distances himself from commercial interpretations of the Metaverse, focusing instead on genuine user-generated experiences.
