My wife asked me something similar. She asked if there were any games where you did not have an opponent. Pretty much every game needs a protagonist and an antagonist to be entertaining. Even her game, Dance Central 2 has antagonists (the Glitteratti and Dr. Whomever for the final match). Shepard never really goes out to kill people, without a good reason, sure you kick an Eclipse mercenary out of a highrise every now and again; but as Mordin said: "Many ways to help people, sometime heal the sick, sometimes kill dangerous people." Or something to that effect.
