The challenge of modelling and balancing the economy of a large scale game is one of the biggest problems game developers face and one that many have tried to solve by simply throwing man-hours at it... But there's a better way! Learn how Gamesys did it by leveraging graph database Neo4j to model the in-game economy of our MMORPG "Here Be Monsters" and automate the balancing process. We'll discuss lessons learned, successes and challenges, and how a graph database enables our small team of game designers to stay agile and focused on delivering new content to players.
