In this GDC 2011 session, Ubisoft's Nicolas Barbeau and Aleissia Laidacker discuss the AI and animation powering the virtual population of Rome in Assassin's Creed: Brotherhood.
The duo go over the concept of crowds, defined as the NPCs which help to make the world of Assassin's Creed feel like a living and breathing environment.
They also explain the difficulties encountered when creating an evolving and changing crowds, like the challenges that popped up in production pipelines and animations.
It was an insightful talk that's definitely still worth watching, so developers shouldn't miss the opportunity to do so now that it's freely available on the official GDC YouTube channel!
