Mass Effect 2 is one of my favorite games of all time. I did notice some pretty bad facial animation but like you it didn't turn me off the game quite as much because the story and characters were so good.you have a point. the facial animations were one of the lowpoints of Mass Effect 2 I remember when I was playing that, but, the rest of the game was SO good that even that was not a detriment to my overall experience.
So I hope Andromeda will be the same. Cause those faces are look pretty rough, so unless the other parts of the game pick up that slack (gameplay, dialogue, story, characters). It's really going to be apparent to me.
