I was not expecting that pick for GOTY after seeing SoM rip through every category it was nominated in :p I'm also struggling to understand how SoM won both "Outstanding Achievement in Animation" and "Outstanding Technical Achievement". I don't really agree with it winning some of the others too, but they're more subjective than the two i mentioned (though i suppose "Achievement in Animation" is fairly open to interpretation).
