He stressed that this won't be the end of the Mass Effect world, just the end of the trilogy. I brought up my dissatisfaction with the end of the Halo story, with Master Chief floating in space. Are people going to be frustrated by the end of the game?
Houston shakes his head. "No, no, no, no. We are absolutely committed to ending Commander Shepard's story at the end of this. I am not going to go into any detail beyond that, but really we want players to feel like the investment they made over the past seven years or whatever it's been, it would have been a rewarding experience for them," he explained.
He said people should want more because they love the world of Mass Effect, not because there are any gaping plot holes or "lanterns left burning." He put it simply: "We want to tie up all the loose ends, put the trilogy to bed, and leave people with the feeling of satisfaction, like reading a really good book."
Amen.
