1) Never played a game where you can make a bad ass looking robot. 2) The race you choose affects how the story plays out. Judging by some of the clips we've seen and the descriptions of the races i think the Exo story will be an interesting one to follow. Awoken are too aloof, and Humans are too familiar. The Exo's have an unknown purpose and general mystery about them that is intriguing to me.
