Well preliminary oppinions so far:
I rather like having a voiced main character. I found being a mute unimmersive in other games. However... Dialogue wheel or whatever people want to use to select responses, it must accurately reflect what will be said and in what tone. I also think there should have been an option, for those who so prefer, to turn voiced main character off... Which only makes, whatever system picked for choosing dialogue, that more important.
Settlements. I %$%$^ love them... They are not perfect and the system is rather clunky, but I've been wishing for this in a long time.
NOT that me:a should have you build shack's on all the planets or anything like that... But the essence of the settlement system could be learned from.
The essence being an outlet for player creativity and individuality. It could be something like furnishing / designing your cabin ... or possibly your ship... Something that the player creates for him/herself and call his/her own.
