Yeah, I always wonder how much more effective the Uncharted series would have been as a fighting game more akin to Arkham Asylum, so Drake is only beating people unconscious and breaking their limbs, not killing HUNDREDS OF PEOPLE!
I mean Batman is dark and macabre as hell yet he refuses to kill anyone, ever, even in the most extreme situations where any court in the world would agree it is justified self-defence to use lethal force.
Really Drake just needs a better reason for killing all these guys than "wow, sum cool treasure".
Think about how Indiana Jones did it that didn't even kill that many people:
OK, well it didn't SEEM like all that many. But with that huge kill count, the people who died were really bad, freaking nazis, cackling Hong Kong Gangsters or child slave drivers who made human sacrifices.
I always thought Uncharted series would have been better going up against some more evil Villains like Human Traffickers and Nate's girlfriend had been kidnapped and had to save her from a fate worse than death. Yeah, rapists would have to be over there with Nazis as "people you would struggle to care about brutally killing".
