Mass Effect director Casey Hudson is in the hotseat for three separate video interviews on GameInformer (here and here) that cover his career at BioWare, the video games and movies that were inspirations for the Mass Effect series, how they've applied feedback from reviews and forums, the challenges involved with naming the series itself and its characters and locations (Excel formulas!), and more.
The videos total nearly 30 minutes worth of footage, so make yourself comfortable if you intend to watch them.
