This new video by PWNED is a veritable cornucopia of BioWare goodness. You've got BioWare's two doctors talking a little about the BioWare process of making RPGs, and you have interviews with voice actors for Femshep and Liara.
The video also contains an interview with BioWare producer Mike Gamble who discusses how altered the universe is at the start of Mass Effect 3.
Finally, you'll see a behind-the-scenes piece on the making of the Mass Effect 3 live action commercial that aired during last night's The Walking Dead.
I feel I should warn the time-impaired, however: this video is almost 20 minutes long.
