Mass Effect had enough plots threads that it's worth a refresher before you hop back into the universe. Not to mention that you'll want to have completed the game if you want Mass Effect 2 to read your old save file and reference all your old misdeeds. Fortunately, BioWare writer Mac Walters is here to walk us through what to see and do in the first game before you unwrap the sequel. Take it away, Mac!"
