Hopefully its cause he just misses home or something... but I smell discord. Doesn't seem right for a game's Director to abandon his/her post a year out from release. I smell EA ****ting on his vision, and directorial refusal to compromise.
Some of the comments are telling.. or at least the nerds who comment on IGN articles are often bang on the money with their guesses and opinions.
Ill still play this for sure and remain cautiously optimistic but I think Mass Effect is in danger of going the way of Destiny. I hope im proven wrong though.
