In this interview, Yuqian Sun, a doctoral researcher at the Royal College of Art, reveals her principles for crafting believable AI Characters, her workflow from story concept to AI prototype, and how cultural nuances shape player interactions. Learn why she avoids pure realism, why she wrote the LONGEST AI disclosure for her released Steam game, and her vision for AI companions beyond gaming.

Before getting into the interview, I wanted to quickly introduce you to today’s sponsor Gracia AI. Gracia AI is the only app that allows you to experience Gaussian Splatting volumetric videos on a standalone headset, either in VR or MR.

It is a truly impressive experience and I recommend you to try it out right now on your Quest or PC-powered headset.
