Lineage is a massively multiplayer online role-playing game played by thousands of players around the world. For the first time ever, we developed two types of multi-agent AI battle content in the Lineage universe using reinforcement learning. Clone Wars and Rookies vs. Veterans offer a chance for users to experience an exhilarating battle against AI opponents. In the future, reinforcement learning will be applied in new ways to create more MMORPG content where users can engage in multiplayer battles with AIs.
Attendees will be able to learn how to develop AIs that can be trained easily even in game environments that are constantly updated. We will also cover reinforcement learning methods we used to train highly complex agents with some practical tips. Lastly, we would like to share a range of issues we faced during the development process and how we solved these problems.

Takeaway

Attendees will be able to learn how to apply reinforcement learning in commercial MMORPG to develop AIs that can engage in large-scale battles (over 20-on-20) against users. They will also learn about the various issues that can arise in the process and how we have dealt with these challenges.

Intended Audience

Researchers who are interested in applying reinforcement learning in commercial games. Developers who want to learn how to design multi-agent AIs and systems in an MMORPG environment.
