i would like to see co op in the main story like having a friend play as a squad mate or perhaps bring their character over and have them become a squad mate in your game and can have a romance with them
have at least as much exploration as mass effect 1
space combat
have your choices matter
keep the combat the way it is in mass effect 3 but amp the RPG elements in just everything else to 1000 and
give a bigger focus on squad commands
