That's right. Content that was conceived for the second game, and refers to the first game, is now in the third. And speaking of things that have been around since the first game, Walters acknowledged the difficulty of continuing the Mass Effect story after the second game's ending, which can kill off important characters.
"The classic example [of a hurdle faced in writing ME3] is 'Hey, let's make the ending of Mass Effect 2 a suicide mission where all your henchmen can possibly die, and Shepard can even die!'" Walters said. "Oh right... and then we're gonna do another game after that. What the hell are we gonna do with all those guys?"
Unfortunately, Walters didn't go on from there. We're going to have to wait until March to find out just what the hell does happen to all those guys.
