Topic: Programming

Format: Session

Vault Recording: Video

Audience Level: Intermediate

Battle system is one of the most vital parts of SaGa and costly to balance due to the huge volume of the game. We present a machine learning (ML) framework to help us balance the battle system of the latest title of the series under development, SaGa Emerald Beyond, with Reinforcement Learning (RL). We show how our game designers use the AI to help their daily work, the challenges, the detail of our in-house algorithm, and the engineering backend to deliver the system. Also, our system and algorithm are generally applicable to other games and address major key challenges on implementing reliable ML system within general production line. With this system, we can evaluate more than 700 stages in one day and find critical bugs, speeding up the QA process significantly.


The attendees will understand the challenges and solutions of implementing reinforcement learning on AAA game battle system, with SaGa as an example.

Intended Audience

The session is intended for AI/Gameplay Programmers, Game Designers, and people who are generally interested in game balancing/QA especially balancing battle system of AAA games. Basic knowledge of programming and reinforcement learning are not pre-requisite, but it would be helpful to have.
