Mac Walters on the Star Child/Reapers
"Originally, with the catalyst, the star child at the end of the game, I had written that much more in the guise of a investigative style conversation, where there is something he tells you but then, you get to ask a bunch of questions and you get your questions answered. But then me and Casey talked and decided, lets keep the conversation "High level". Give you the details that you need to know, but don't get into the stuff that you don't need to know. Like "How long have they been reaping?" You don't need to know the answers to the mass effect universe. So we intentionally left those out"



Casey on after Mass Effect 3
"Whatever we do would likely happen before or during the events of Mass Effect 3, not after"



On delaying the game
In march 2011, he also faced a roomful of Mass Effect developers who expressed concern about hitting the promised holiday release date... New release date set for March 2012. After much deliberation, the CAT mission (or rather, the Prothean mission) had to be removed from the set of tasks. The missions would later be completed as post-release content"



Casey on the End Boss
We had the final fight with the Illusive man in the game, but it just felt very Video Gamey. It didnt fit in with the themes. And really, is there a point of the end boss if only for the sake of an end boss?



On Tali's Face
We eventually decided that she gives you a memento of her pictures, but the team was throwing around a lot of pictures and designs until we decided on something and said "Yup, that's her".



On Deciding the End of the Game
The illusive man boss fight had been scrapped... but there was still much debate. On night walters scribbled down some thought on various ways the game could end with the line "Lots of speculation for Everyone!" at the bottom of the page.

And even in November the gameplay team was still experimenting with an endgame sequence where players would suddenly lose control of Shepard's movement and fall under full reaper control. (This sequence was dropped because the gaemplay mechanic proved too troublesome to implement alongside dialogue choices).

Deleted Scenes Videos:
- Liara and Garrus are running behind sheppard in the run for the conduit. Garrus falls over and Liara tries to pick him up. As he gets up, the two run and are hit by a laser as sheppard watches on without hope. In the final version (which is shown beside the deleted scenes video.) the body of your team mates are on the floor dead instead.

They discuss the dialogue for anderson they cut as well. Everyone on their team liked it but Casey said it was "too long for the moment".
