"I had a great time at BioWare, working with so many talented, passionate folks," Harris said in a tweet. "I'm grateful for everything you taught me over the years."

Harris is the third notable departure from BioWare this year alone. Mass Effect: Andromeda lead writer Chris Schlerf left in February to join Destiny studio Bungie, and long-time Dragon Age lead writer David Gaider exited in January.

Harris gave a talk at GDC 2014 on the importance of editors in creating strong video game stories, and we've embedded that presentation below.
