As far as I understand it the N7 character we see is not the player character.
From the forum: "You will play a human, male or female, though that’s actually not the character you saw in the trailer (more on that later). You’ll be exploring an all-new galaxy, Andromeda, and piloting the new and improved Mako you saw. And through it all, you will have a new team of adventurers to work with, learn from, fight alongside of, and fall in love with."
Sound like they are going the exploration root with this one, which can be interesting. I just hope if they make big maps they actually make them interesting. I did not like the open world in DAI, too many pointless fetch quests.
