Creating a world of dynamically shifting alliances and intriguing diplomatic exchanges between over 40 factions while making sure the player is having fun is not a small challenge in a sandbox grand strategy game. This retrospective talk reveals how the developers implemented the Diplomacy AI in Total War: Three Kingdoms, how they re-shaped the system they had carried over from our previous game, what techniques, tricks and design philosophy they used, and how this impacted the game's overall quality.

In this multi-disciplinary talk, Senior AI Programmer Duygu Cakmak will explain the technical implementation of the system, while Senior Game Designer Csaba Toth will focus on the design and finetuning part of the topic.


The audience will leave with an understanding of how the Creative Assembly team tackled the challenge of creating a utility AI system for handling Diplomacy in Total War: Three Kingdoms, how data driven decision making can provide flexibility and how this can help designers in balancing the game.

Intended Audience

Any AI programmer or game designer with an interest in strategy games. Producers and dev managers may also find the programmer-designer collaboration aspect of it interesting.
