Geek and Sundry is offering a pretty long (more than 30 minutes) and in-depth video interview with BioWare's lead writer David Gaider, who worked on titles that range from Baldur's Gate II: Shadows of Amn to Dragon Age: Origins and its sequel. Notable subjects tackled include the differences in the writing process compared to scriptwriting in movies or series, whether introducing romances was a risky move on BioWare's part, the "artistic integrity" debate and more.
Additionally, for anyone that cares about the detail, actress/scriptwriter Felicia Day is the interviewer.
